I have a 1993 2wd manual pickup fuel injected 22re.
When I bought it I was told it wouldn't run because of a bad fuel pump

I replaced the fuel pump, injectors, fuel pressure regulator, fuel filter, and completely cleaned the tank. I'm getting good pressure all the way to the cold start injector so I know fuel is not a problem.
(By the way fuel pump was not getting power through stock harness so I ran a toggle switch to manually turn it on and off)

Truck still wouldn't stay running after starting fluid got used up.

I replaced the whole computer unit on top of the airbox, and the actual computer inside down by the passenger footwell. So all of the computer parts are fine.

The truck is in time, I made sure of that and also changed all of the spark plugs and get fire to all of them when individually holding them against the block.

Each cylinder gives good pressure readings about 150 for all of them so nothing is wrong internally.

All of the fuses are fine and after all of this the truck still will not run, any help is greatly appreciated

 

Have you checked the Circuit Opening relay? AFM?

I'm not thinking the toggle on the fuel pump is such a great idea if you get in a accident, IMHO.

 

I replaced the whole module, can you explain about the circuit opening relay?

 

The COR is just a relay for your fuel pump. X2 on getting rid of the toggle switch for it.

 

Is there any way I can check the COR without replacing it, I'm really hoping to get this thing on the road soon.

Thx

 

You can check it like a regular relay. There not to expensive if you have to replace it.

 

Problem fixed it was main relay under dash thx to all
