1. 1999 jetta (gas) no signal to injectors
Hello all
I have a 1999 jetta that has stopped running. It has a new fuel pump relay and the pressure at the fuel rail is good. Also new coil, plugs, and wires. The throttle body has also been completly cleaned.
If you spray starter fluid in the throttle body it starts up for a few seconds.
I put the noid lights on the injector connector but had no signal at all. Ran the scanner and got codes
po303
p1300
p1225
p1226
p1227
p1228
p1425
p1472
p1582
p0102
The codes overlap some of the issues but it seems to indicate a short circut in the evap or fuel system. Need to know if anyone has been down this rbefore and where to look next.
Thanks
Larry

P0303 - Cyinder 3 misfire detected.
P1300 - Unable to find any information our database but should be related to P0300
P1225 - Cylinder 1 injector circuit shorted to ground
P1226 - Cylinder 2 injector circuit shorted to ground
P1227 - Cylinder 3 injector circuit shorted to ground
P1228 - Cylinder 4 injector circuit shorted to ground
P1425 - Tank Vent Valve shorted to ground
P1472 - EVAP emission control LDP circuit short to ground
P1582 - Idle Adaptation at limit.
P0102 - Mass or Volume Air Flow Circuit Low Input.

Since vehicle is not starting, I would suggest starting with the injector circuit first.

FUEL INJECTORS, CHECKING
Checking activation

Check activation of fuel injectors.

Special tools, testers and auxiliary items

a) VAG 1598/18 test box
b) Multimeter (Fluke 83 or equivalent)
c) VAG 1527B voltage tester
d) Connector test kit VW 1594
e) Wiring diagram

Check conditions

a) Engine speed sensor OK
b) Fuel pump relay OK

Test sequence

Remove intake manifold, upper, see Fig. 2, item 7.
Disconnect harness connector -1- from connection -2- and connect VAG 1527B voltage tester with test leads from VW 1594 to the terminals of the harness connector.

Disconnect harness connectors from fuel injectors 2-4.

Operate starter and check the voltage supply for no. 1 cyl. Fuel injector.

LED must flicker

Repeat check on fuel injectors 2-4.

If the LED does not flicker:

Turn off ignition.

Connect VAG 1598/18 test box to ECM wiring harness.
Fig. 118: Connecting VAG 1598/18 Test Box To ECM Wiring Harness

Check wiring between test box and connector for open circuit according to wiring diagram.

No. 1 cyl. Fuel injector: terminal 2 and test box socket 24

No. 2 cyl. Fuel injector: terminal 2 and test box socket 25

No. 3 cyl. Fuel injector: terminal 2 and test box socket 26

No. 4 cyl. Fuel injector: terminal 2 and test box socket 02

Resistance: maximum1.5 ohms (ohm)
Fig. 119: Checking Wiring Between Test Box And Fuel Injector Connector

Check wiring between fuel injector connector terminal 1 and relay panel for open circuit according to wiring diagram.

Resistance: maximum 1.5 ohms (ohm)

Additionally, check wires for short circuit to one another.

Specification: "infinity" ohms (ohm)

Checking resistance of fuel injectors

Check resistance of fuel injectors individually
Fig. 120: Checking Resistance Of Fuel Injectors

Specification: 15-20 ohms (ohm)

If the specification is not attained, replace fuel injector(s) as necessary.

Check out the diagrams (Below). Please let us know what you find.

The fuel pump relay has been replaced.
Could this be an issue with the ignition switch?
The cruise control stopped working right before all this happened.

If it is an ignition switch problem, you would not be getting any sparks as well.

At the injector circuit, ensure there is battery voltage at the RED/Violet wire with ignition switch turned on and while cranking. If voltage is available, the fuel pump relay is working correctly.

The cruise control is linked to the ECM. Check fuse # 5 in fuse panel behind left sie of dash. Use a DVOM to check the Black. Blue wire for battery voltage with inition switch turned on. If voltage is available, ensure White/Yellow wire from switch has battery voltage. If voltae is available, you could have a faulty ECM.

Check all fuses under hood and in vehicle. If the wires touched, they shorted. The first thing should have been a fuse. Remove the fuse that is in the affected circuit and check it for continuity. It could look good but still need replaced.

The next time it does not start, leave the key in the ON position. Is the CHECK ENGINE light on?

The check engine light should be ON when the key is ON. If not, then the Engine Computer is NOT powered up.

Could be a bad ECM relay.

That could very well be the case, try to undo the negative cable on the car battery for fifteen minutes and then put it back on and then try.

Ignition key will have to be re programmed so the key reader and PCM can read the chip in the key.

I bought a used 95 Jetta III about 9 months ago. Everything was running fine until around late December when I stopped and got gas and the car wouldn't start after I was done pumping. I had it towed to a garage and had the starter replaced and everything was fine. A few months later, I get out of work on a relatively warm day and the car won't start. No noise came from the car. No crank. Nothing. All of the lights turned on and the radio work as well which made me think it wasn't a battery problem. But I thought it couldn't hurt to try and jump it. Still nothing. I had it towed back to my mechanic and it started fine for him which confused me even more. A few months pass and one morning it doesn't start again. Same thing, no crank, all the electrical aspects work, but every now and then when I try and turn it over there is a slight grinding noise coming from the engine. I replace the battery and still nothing. So I have it towed back to the same mechanic and they replace the spark plug coil and the fuel pump sensor and it starts fine for about a month. Now it seems to not start on hot days and/or when it's been sitting out in the sun. I have looked online for answers and I have noticed that there are a few common problems with this year's model. Any ideas on what the problem might be and how to fix it?

I would look at the connection on the starter motor. The little wire may not be making good contact.

1990 Volkswagen Jetta cranks over but doesnt start

Why don't you do this before you think! Computer to determine if its a fuel or spark problem

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, distributor pick-up coil, ignition control module, cam and crank sensors- Note: If it doesn't apply disregard it

Thanks for your response. We have done all that you suggested and determined that my fuel pump is shoot and my spark is intermitten (?) Even after the new coil (bosch). But still no start. My mechanic said something like the ecu isnt giving the "go" signal for everything to work. It would help him troubleshoot if he had the ECU wiring diagram. Would it be possible to email me one?

Hey Guys, I have a 1997 Volkswagon Jetta and I've recently had issues getting it stated. The temperature recently change and it started of intermitten at first, with the cold weather it wouldn't turn over and when it was warm it would strugle like the engine was choking and then fire up. Well now, it hasn't started in a couple of days hot or cold and I've tested the battery which is still good so i've ruled out battery and alternator. I did have real bad corosion issues with my terminal posts but the test came back positive so the next step I can think of is the starter, I was told this is also a common sympton of a faulty ECU. Would you say I"m on the right track and do you know of any other possibilities? I was told this is also a common sympton of a faulty ECU.

If its cranking over and will not start-Do below

Cranks and w/n start

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it

No crank at all/nothing/nada:

Could be the starter, starter relay, park and neutral switch and ignition switch assuming the battery and connections are good.
