Truck started stalling at idle. Thought it was the fuel pump getting hot replaced it same problem occurred. Drove it to up the street died hasn’t started since. Any ideas?

 

37 is TCC solenoid circuit? I think, that should have nothing to do with not starting. However, if the trans relay isn't getting triggered, is the ASD relay? Does the fuel pump prime when you first turn the key on?

 

What engine and transmission are in your truck? Gas or diesel? Is the battery in good shape?

 

yes primes. Will start for about 3 seconds then it’s like the fuel is cut off. Not sure what’s causing it. I bridged the ASD relay and it still wouldn’t start.

 

5.2 318. Stock transmission not sure what it is. It’s my first dodge. Gasser. Battery is a cheaper one but seems fine.

 

Will it stay running if you give it some gas??

 

No. Dies immediately when I hit the gas. Only runs for about 3 seconds before it dies anyways.

 

I might be tempted to check fuel pressure, even though you have a 'new' pump. Especially if its an AirTex brand pump... (they suck....)

That it only runs for three seconds though is highly suspicious..... PCM will engage ASD relay, and fuel pump for.... wait for it.... three seconds...... unless it sees the engine turning... Since it is firing the plugs, that implies it is indeed seeing the engine turning......

Will it immediately restart and run for another three seconds?

 

no it has to be primed back up. I put direct power to the fuel pump had fuel pressure but it would still only run for about 3 seconds then sputter out.

 

Was it maintaining fuel pressure when you had it hard wired?
