Car Starting Problem

[5ky]

hey guys, i got my motor replaced, and then it been running fine for a few days, until then, when it hits full boost, car would jerk and then stall, after it stalls, it wont crank over again, car just wouldnt start, its a 50/50 chance it would start up again, i have tested and swaped coils, change spark plugs, tested injectors to be ticking, checked afm, and pulled out the fuel hose, and seeing if any fuel was coming out, and it did, so fuel pump is all good, compression tested motor, it was good, car is a 93 r33 gtst and i replaced it with a 95 motor, I also changed the ecu to a 95 model ecu, but still no luck.......... i have checked all piping to see anything loose, but everything seems fine? what could be the problem? am i missing out on something?

Tune....?If not re-set computer then get it tuned later.

There is a section on this Forum to do this.

sometimes when it starts, it will booost normally, maybe after 30min-1 hr it will then jerk and stall, and wont start up again

Just because fuel comes out, doesn't mean it is ok. Check to make sure you have the correct pressure and flow. Until you test these, you cannot assume your fuel pump is still ok. Your problem sounds fuel related.

Whats full boost mate?

std ecu R&R maybe? But that wouldnt explain the not starting again. As elite 32 said it does sound like a fuel problem, more so lack of up high.

So you changed motor, loom and ecu or are all r33 looms the same from a series 1 and series 1.5?

[5ky]

running 93 loom and ecu, and 95 motor

but i changed it to a 95 ecu too but it still doesnt start up, arent all series 1 loom the same?

im pretty sure the 1.5 only has the interior difference, but mechanical the same

only the series 2 were different
