Put new EC module, IT module, distributor EGR valve, coil, TP sensor and fuel pump works. The car cranks but will not fire.


What's missing ? Spark , fuel pressure , or compression. Try spraying carb cleaner into the engine ,throttle plate . Does it try to start then ? If the injectors are bad it will not start , just crank ! Videos on youtube showing how to test fuel injectors with a ohm meter .

No gas coming out the injector and there is gas pressure to the injector?


Is there an injector pulse going to the injector?(an electrical pulse to fire the injector).
Is there spark at the plugs?
If the pickup in the dist is faulty you won't have either one.
If your vehicle uses a crank pickup with or instead of dist pick up....if it is defective ....no pulse.
The above is 90% cause of no pulse....other is computer problem 10%.
If you do have a injector pulse and no spray.....and have fuel pressure....change the injector.
A quick check for spark is spray a little starting fluid in it.....if it starts on the fluid....spark is present.

Good spark -- fuel supply line has fuel -- will not start -- either sprayed into air intake -- car immediately fires -- why are cylinders not getting fuel?


possibly a bad pressure regulator or injector module not letting the injectors fire. check out both more than likely the injectors are not firing.

Crank no start: has no spark and only has injector pulse on cyl # 1. if you spray starting fluid directly into throttle body car starts and stays running and has spark and inj. pulse. once you turn the car...


Fuel pump, you have to have press in the rail to fire all injectors- she will run on ether but not good for her. Ck your pump and any related fuses,relays,wiring.

Throttle body injectors not fiering but there is fuel pressure


the injectors are fired thru the engine cotrol module but it gets its signal to fire from the pick-up located inside the distributor if you are loosing injector pulse only the ignition module is bad if you are also loosing spark when you loose injector pulse your pick up is causing the problem if you replace the pick-up i recomend you change the ignition module when doing so because they work together and you have to remove the distributor to change the pick-up

Car won't start


check backnnector on distributor assy. It's hard to find because is on the side just in the point nobody reach. Often it missconnect or broke. check, fix or re adjust as needed. check firing order of cables If not result.... 1.-unplug any spark cable and put a screwdriver inside it and place it in a safe place near a ground point. The object is try to see the spark jumping to ground. 1 or 2 cm will work for it. If you see spark, check fuel pump circuitry. uncap carburator and see if injectors spray gas when you try to engine. If you can see spark, change module inside the distributor cap.
if injector doesn't spray,check fuel pump, you must hear it for few seconds when you turn key to accs if you place your ear near thank. fuel pump work for few seconds but no spray on injectors: the same module above mentioned. if injector sprays and spark jump, the car must start
