I have a no start issue. The car cranks but will not start. I have no spark ans no power to any of my sensors. I do have power to my coil pack and fuel pump, but my fuel pump will not kick on. I also have a no link when I connect the OBD reader. I have replaced the crankshaft sensor, the camshaft sensor, the fuel pump and one fuel pump relay's. I also replaced spark plugs wires, spark plugs, coil packs and three injectors.
also, when I test for a short using the method of a test light n the negative cable and pulling the fuses one by one the light turns of on the fuse with the picture of car door unlocking, meaning the anti-theft fuse. How can I fix my problem?

Hello,

It sounds like you have an MFI relay that is out or a fuse that is blown here are guides to help you do some testing a long with the relay and fuse locations. Also, check the fusible links as well.

Thank you so much for responding ive checked all the fuses all of them are good except when I first did the finding a short test by disconnecting the negative and clipping the test like from the connecter and the post of the negative battery the light was on then I pulled each fuse one by one until the light shut off which was the fuse that controls the lock and unlock the antitheft fuse 13 I believe the fuse was not blown tho I have no power going to my oxygen sensor camshaft crankshaft sensor I do have power to coil packs the car does crank and there is power going to my fuel pump even with starter fluid being used the car still wont turn on the timing is correct on the car the check engine light also does not turn on in the dash im guessing thats why the obd reader says no link so I will look at all the diagrams u sent me and work on it also the problem started on a cold morning I went out to warm up the car and all of a sudden it turned off n ever since then it hasnt turned back on

Yep it is sounding more like the MFI relay or the power source to the relay please use a test light and check when you can.

I guessed on the wiring n connected the white the black n copper wite together and left the brown trigger wire alone n connected the red to the black and red ignition wire to get power to the sensor when I move the wiring I hear a poopping noisr from the fuse box meanig something is not connected correctly I cant find a wiring diagram anywhere for the front oxygen sensor

The wiring for the oxygen sensor are on the third wiring diagram over toward the top. Let me know if you need further instruction.

That code is for the camshaft position sensor. I am wondering if you have a timing belt that is slipping or moved a tooth. Have you done a timing belt on it or can you confirm that it is correct?

Here is a guide

let me know have a good weekend!

Lets check for where you are losing power. Here is a guide and a wiring diagram to help you do some testing.

It doesn't seem to have a starter relay.

Lets start from the beginning. Please check if you have compression. Here is a guide.

Yep we are getting closer. Lets check for injector pulse to see if the injectors are getting a signal.

Please let us know what happens.

Can we plug all spark plugs and keep them in order then take a picture of the electrodes and upload them here so I can see what they look like.

Yes, sorry it has taken me so long to respond still have the same issue. I will take a picture of the spark plugs. Each one has spark there is compression and fuel, but just cranks no start. Also, used starting fluid still nothing. Tried push starting it also nothing. Just keeps cranking. On the dash the battery and the oil light stays on. I believe the only light that turns off on the dash when cranking or on position is the check engine.

The fact that it has compression and spark and you use starting fluid but it still will not run is telling me you may have a plugged catalytic converter which will allow exhaust to exit the engine. Here is a guide to help confirm the issue:

Please run down this guide and report back.

Okay, water pump went out changed pump, timing belt all gaskets back together and no start. Started checking and double checking made sure everything was plugged in double checked timing checked fuel fuel pressure excellent no power to coil. Replaced crank, cam sensor, replace ECM still no fire. Started checking relays none found to be bad. Cam censor not putting out enough voltage only 4.6V. So replaced thinking maybe a defect, no start I have even chased wiring harness checking to see if I pinched a wire or maybe I broke one no problems found. I am at a loss. What do I do from here?
