95 camaro 3.4 wont start
#11
Ok i have replace the TPS,ICM,TEMP SENS. CHECKED ALL FUSES CHECKED EACH COIL PACK CHECKED FUEL PSI. WITHOUT GIVING IT GAS IT TRYS TO START BUT IF I GIVE IT GAS IT WONT TRY AT ALL IF I KEEP TURNING KEY OFF AND THEN ON TO START IT TRYS TO START. GRRRR ITS GETTING ME AGRIVATED IN THE END IT WILL PROBLY BE SOMETHING SIMPLE. SO WITH ALL IVE DONE AND SAID ANYMORE IDEAS GUYS

So it boggs out when you try to give it gas.
What do you think craby, MAF sensor?
Have you taken craby advice and see if someone can hook it up and see if the injectors are actually firing when they are supposed to?
Tthose are the only 2 things I can think of that it would be after all that.
My bet is on the MAF sensor, but I could see crabys idea of the injectors too.

need to know if the injectors are firing. it takes fuel and spark to fire and you are saying you have both with no fire. sooo im gona say one is missing in one way or another. have you sprayed a little gas or starting fluid in the throttle body to see if it will fire up for a couple seconds.

Based on what I'm reading, best bet would be to test for connection to the injectors. Have yet to try this on a camaro but I just recently tested them on my cadillac. easiest way (testing ohms)is to remove the plug(s) from the ecu, find out which wires go to each injector, and use a multimeter to test connectivity between each injector wire and the corresponding injector fuse(1 fuse powers half, the other powers the other half).
If there IS connectivity then odds are, that is not your problem, but write down the ohms for each injector for future reference. If there ISNT connectivity, then that means somewhere in the circuit is a break and your injectors arent getting any power. Fuses, fusible links (if these cars have em), wiring, etc need to be checked. I'm sure there is someone on here with a wiring diagram or pinout that can help you with the specifics.
