car runs for 10 seconds then stalls

[turbospirites]

I have a 1990 dodge spirit es it has the fwd stage 5 computer +40 injectors billet fuel rail 3/8 stainless fuel lines 3" exhaust ect...I prime it a few times it starts and runs for 10 seconds then stalls. I checked the map nothing wrong with it.I'm confused

Any codes?

Try the stock computer if you have one and see what happens. If you run a stock computer with the 3 bar and +40's, it runs like it has a 2 bar and stock injectors, but leaner.

12 and 14 codes does the same thing i need to get a aftermarket fuel pressure gauge because the billet fuel rail don't have a connector for testing fuel pressure.

on the map sensor i cant remember what barb is what on the 90 spirit vac hose on the 1st barb, second one is the map?

I think your car has just decided your ET goal for you.

Huh? There is only one barb on the MAP sensor, that goes to the Baro solenoid which goes to manifold vacuum.

14 is the MAP sensor, so if you've got it hooked up wrong, that will cause your stalling.

ok on the baro sensor the top one is the one going to vacuum the one below it is going to the map sensor.

Correct, but it only goes one way.

i was thinking the same thing. 10 secs is enough if you live your life a quater-mile at a time!

Exactly

[sexygomer]

try and just hook the vac line straight to the MAP, the solenoid can be bypassed, see if that helps, make sure you have a good line/source (that isn't collapsing on you) to it

Does it barely run or will it idle fine and then just die?

[turbospirites]

It idle's fine then all of a sudden it dies like it ran out of fuel. When you get it warmed up hit the gas at 3k rpms it stays running but as soon as you get it to idle it dies.I tried to hook the map to a vacuum line straight no luck.I might need a larger fuel pump then the Walbro 225 pph.

well got it running. Now a bottom end rod knock I'm just going to go out find a 2.5l n/a block put the turbo pistons and rods in it I am getting tired of this old pos!

89-up 2.5 blocks and cranks are all the same, turbo or non-turbo. So you should be fine. Just have to drill a hole for the oil return in the back of the block.

[tsiconquest88]

really? i figured there was better rods or soemthing for turbo to NA blocks? At least lol. So what your saying is the NA 2.5 is so good it was tossed to the turbo wolve and found to be good? lol sorry went off on a spree there. I just cant beleive the NA and turbo are the same. Thats pretty cool actually.

[contraption22]

The blocks and cranks are the same. The rods and pistons are beefier in turbo motors. He had said he planned to swap in turbo rods ands pistons in to the N/A block.

[tsiconquest88]

oh ok, i figured as much, i thought when u said the 89 up 2.5 turbo and NA were the same, you meant both had the exact same parts.

[turbospirites]

yea plus the N/A blocks don't have the oil return on it I don't need it because i have a oil drain back on my oil pan because the turbo is huge and i cant use the factory return port.

[TurboII]

did the block have alot of miles. The bottom end shouldn't knock like that out of random?
