Hello,

my 1982 crossfire is getting gas to the carborator but will not crank. can you help

 

1- crossfire does not have carburaters.
2- not cranking- you turn the key and nothing happens? starter issue?

You may need to explain in more detail whats happening or not happening with your car to get advise.

 

so if you take the air cleaner off, as you try to crank it you see fuel swirling out of the two throttle bodies? Have you check for spark?

 

Fuel pump is electric; if you have fuel at the TBI, you have battery. If you have battery and the car will not crank, check the starter circuit.

Tranny in Park or Neutral?

 

it is in park. It has new starter and new fuel pump.

 

It will crank and start as long as you pour gas into the barrel.

 

when you turn the key it turns over and spins engine fine and it is getting gas to the throttle base but will not crank until you pour gas into the throttle barrell.

 

I don't understand what you mean.

Explain it better.

This is what is should do. Open the hood and take the cleaner off. Turn the key to the on position but not all the way so it cranks.

Do you hear the fuel pump buzz for a second or two...listen behind you.

Do you hear a funny noise from the injectors and see a burst of fuel right after the pump noise?

When you crank the engine do the injectors spray fuel?

While cranking it does the oil pressure climb? Look at the gauge.

Report back.

Do you have a check engine light with the key on?

 

Are you sure fuel is being pumped to the TBI? You say you are pouring fuel into the TBI. A. That's dangerous. B. You shouldn't have to do it.

Does the car fire at all?

 

It sounds like your engine does crank (starter turns motor) and you do not have fuel at the TBI's if you have to pour gas into the motor to keep it running. There are many reasons to have low fuel pressure at the TBI's. Most likely culprit is the pump which is in your gas tank. Clogged fuel filter is another area to check (frame under passenger foot area). You described a carb in your first post, do you still have the crossfire on the engine?

 

Hey,
Im having the same issue. My fuel injectyors dont fire until I shoot some gas into the intake. If I do this the car runs ok. I already changed the pump and filter.. Did you get any suggestions?

 

With the limited information supplied I can only guess. If when you turn the key the engine turns over and you have spark check the following:

1)Fuses

2) The connections on the driver side of the distributor.

3) The connector on the oil pressure sensor located on the driver side of the block at the very rear just down beside the head.

4) The connections at the ECM and the ECM fuse.

Once again, I need answers to the above to figure it out.

 

I had "almost" the same problem! In my case the engine would start for a few seconds if I primed the intake with a little gas. I bought a "noid" light ($10) at the autoparts, this plugged into the injector wiring harness; when I turned the key I saw flashing in the light. This told me that the injectors were getting power and should be squirting gas, but no fuel was coming out. Assuming the injectors weren't plugged, that told me that I had no fuel pressure, that explained why priming it would get it to fire for a few seconds.

I next found the wiring plug going into the fuel tank near the filler tube, I unplugged it and used a trickle charger to power the fuel pump (there are 3 wires going into the tank, 1 for the fuel gage, 1 to the pump, and 1 for a ground). I could hear the pump running for a few seconds, so I turned the starter and the engine was running. This confirmed my suspension that the fuel pump relay was bad.

As I understand it, the fuel pump relay comes on for only a few seconds after you turn the key on. This gives power to the fuel pump for a few seconds to charge the fuel system, so you have time to hit the starter. When the engine starts the oil pressure switch senses that the engine is running and provides constant power to hold the fuel pump on. This circuit is designed to turn the fuel pump off in case of an accident or loss of the oil pressure, for example. Without constant oil pressure, the fuel supply is stopped.

I hope this helps a little.
