Gm has lots of problems with passkey anti theft/start system. Do you have another key for ignition try that first. System may not be picking up on chip in the key. There is proper procedure on resetting or programming the pass key/system.

Ive got fuel at the injector rod on my 1994 v8 jeep grand cherokee larado but the car wont start .. this all comes after runnin out of gas. its almost wasnts to but doesnt stay on at times and now won


If you ran out of gas there is a very good chance that the fuel pump relay has blown a fuse or requires a reset. Fuses and relays are in the main fuse box behind battery. When you turn your ignition on to the one setting before the starter engages you should be able to hear the fuel pump running. If it does not then check those fuses. If it does run then there is a good chance that the crank shaft positioning sensor needs replacement.

I changed the spark plugs and wires ive double check firing order , still wont start i also arc the a arm w starter just for a sec , ive checked fueses


Does it crank? If yes, do you have fuel pressure? Needs 55-62 psi of pressure.(Blazers eat fuel pumps like candy, and this one is inside the fuel tank) Is the check engine light on? May have a cam or crank sensor fault. Need to be certain before throwing parts at it. The fuel pressure test port is right on top of the intake manifold. There may be a factory security system that's been activated, do you have the key fob?

Car cuts off and gets harder to crank


A bad O2 sensor would not prevent it from starting. The computer ignores the O2 sensor until the engine warms up. If the fuel pressure is good, check the engine coolant temp sensor. If that's bad, the computer may think the engine is warmer/colder than it really is and will give the wrong air/fuel mixture.

05 c240 turns over won't start


most likely you have a bad crank sensor or fuel problem you need to check fuel pressure ,if you have enough pressure ,most likely you need crank position sensor,if you don`t have fuel pressure ,it might be your fuel pump relay or the pump, i would start with the relay first very unexpensive. you can also hear the pump if it`s working by cranking the engine and listening rear of the car for a humming sound .
good luck

Make sure battery has a full charge. Have a helper crank it, while you visually check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure. Also, check fuel injector pulse.

Engine cranks but wont start


Usually if no rpm signal, the vehicle won't start. Engine cranking, did you check for spark at the spark plugs? The fuel pressure you listed may have been the initial prime. It sounds like no injector pulse. The rpm signal comes from crank sensor. If your missing rpm signal, may thought is the crank sensor.
Were there any applicable trouble codes?

My s10 will turn over, but wont squirt gas through injecter


Does it crank? Do you have any codes? Check engine light? Do you have spark? No spark check coil, and connections, also it would be nice to know what year it is. Get codes read. No crank check battery and starter. No codes or lights check crank position sensor, make sure your pcm is good after replacing your ignition mod you could have blown it if you did do it right. (engine computer) Check cam sensor if applies. Crank and cam could prevent it from starting and I know one I think cam controls pcm's fuel delivery on gm's
