I have a 1999 Dodge Dakota 2wd 6cyl. When I try to start it does not start. I replaced the battery about a week ago and still nothing. I had tried pumping the gas pedal and got it started that way, but when I let off the gas it stalled. Do you think it sounds like the fuel pump, or spark plugs. The spark plugs have never been changed either.

None of those things will fail from replacing the battery but the Engine Computer will lose its memory. It has to relearn "minimum throttle" before it will know when to be in control of idle speed. To meet the conditions for that to to take place drive at highway speed with the engine warmed up, then coast for at least seven seconds without touching the brake or gas pedals.

All the voltage checks come back good as in 5.0 vdc and 12vdc where the book says check

Have to jumper the fuel pump relay to get fuel at the fuel pump remove jumper it stays running turn car off then back on it starts go in the house come back out and have to jumper the fuel relay to start to get 12vdc to pump

LDP Clicks and works dont know what is telling the PCM to not engage the fuel relay and the ASD relay
New PCM New CPS New fuel

Help

You need to back up and find out what else may not be working.

All "crank, no start" conditions are approached in the same way. Every engine requires certain functions to be able to run. Some of these functions rely on specific components to work and some components are part of more than one function so it is important to see the whole picture to be able to conclude anything about what may have failed. Also, these functions can ONLY be tested during the failure. Any other time and they will simply test good because the problem isn't present at the moment.
If you approach this in any other way, you are merely guessing and that only serves to replace unnecessary parts and wastes money.

Every engine requires spark, fuel and compression to run. That's what we have to look for.

These are the basics that need to be tested and will give us the info required to isolate a cause.

1) Test for spark at the plug end of the wire using a spark tester. If none found, check for power supply on the + terminal of the coil with the key on.

2) Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.

3) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.

4) If all of these things check good, then you would need to do a complete compression test.

Once you have determined which of these functions has dropped out,
you will know which system is having the problem.

Check engine light on
Have the computer scanned for code/s-you have a problem within the engine management system that caused the CEL to turn on-This is your starting point of diagnosis, finding out what's going on.

Use a gage and check fuel pressure. What is the fuel pressure spec, engine cranking. Check for applicable trouble codes, anything? How long since a tune-up?

My truck was off the road for five months it started right up when I returned it to the road but it soon started to skip and backfire and buck so bad it was not driveable I added dry gas to it which seemed to help I replaced the plugs and it ran good for a day then started to repeat the same thing I got it home and the next morning it started right up I started for work and it was skipping and backfiring so bad I had to turn around a 1/4 mile from home and barely made it home it has not started since we replaced the dis. Cap, rotor and wires. It acts like it not getting any spark.

Do below to determine if its fuel or spark then get back

Get a starting fluid/ether/better off gas in a spray bottle and spray into the carb or the throttle body on an EFI. Did it start and die? If not 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

You need to check for fuel pressure and for spark
and let us know what is missing
give the gas tank a tap or two while a helper trying to start and if it start you need a new fuel pump
check fuses and relays

The truck will turn but will not start. And every time I replaced a part it would not start after couple of month later. So I have replaced the PCM, idle position sensor the battery. Checked the fuel pump n hear the buzz unless I was mistaken. I've checkedwith volt meter on the sensors but not sure if I checked them correctly. Please help Me for I have been here stuck for few days.

Did you check for applicable trouble codes before you did, anything? If you replaced the pcm, may need to have it programmed by dealership. If it cranks good but won't start, have a helper crank it while you visually check for spark at the spark plugs, if you have spark everywhere, use a gage and check fuel pressure, engine cranking.

What about security system? Just mentioning a few possibilities.

Yeah ur right about the PCM needing to be programmed it was done. And it was great for 6 month and it wouldn't start again. Well, now I'm checking the spark plugs n the fuel injectors n bought myself a scanner. If u have ne other suggestion would be appreciated.

This truck seems to have no power and its really bad in reverse. I tried loading it onto a trailor and unless I got a running start it wouldn't make it. It starts fine and idles alittle rough but it has no guts. What can I look for?

Lack of acceleration, chugging, hesitating, jerking, bogging, misfiring etc. Could be caused by one of the following below

Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Crankshaft position sensor
Knock sensor
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
False air leakage.
Fuel contamination.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
Incorrect ignition timing.
Cap and rotor.

Note:If it doesn't apply disregard it
