i just dont get it...

[jtroy917]

pulled the rail and fuel just poured out...so i know im gettin pressure..
pulled the plugs and grounded each one and saw a nice spark...
bought a new ecu and main relay...
it cranks...and cranks... sputter....but it wont start.. i dont get it...
ive checked out the marks. Everything is at TDC.
and another thing.. ---why does my upper intercooler pipe get hot during crank? is that normal?

I figured out where your fuel and spark are going.

Have any compression?

You might check your ignition control module "power transistor" down by the coil pak. If it's bad, the car won't start.

yea, i got compression.. sittin at 140-160.....
and i got 2 transistors.. 1 looks like it has a bad electrical burn (that white stuff usually found in a dizzy cap, forgot what its called..)
and the 2nd one i tried and still same issue; 1 question about it, does it have to be mounted?

And theres a little capacitor sitting on the intake manifold... is that for the coilpack? and how important is it?. I may need a new one.

--but i still dont understand the hot upper ic pipe.. ????

Right....because that's an accurate way to test fuel pressure.

pulled the plugs and grounded each one and saw a nice spark...

Again, doesn't tell you whether the plug is firing under compression or not.

bought a new ecu and main relay...

So you're throwing parts at the car without knowing if it's a spark-related or fuel-related issue.

it cranks...and cranks... sputter....but it wont start.. i dont get it...

Have you tried using starting fluid to see if the engine will fire? This would obviously rule out a spark issue.

and another thing.. ---why does my upper intercooler pipe get hot during crank?

If there's no combustion happening there's no boost from the turbo....so there's no way the cold-side of the intercooler piping would be warm.

thanks all that info actually made me facepalm myself a few times over.. haha. but how would i test if the plug is firing under compression?

A little bit of starting fluid. If it starts to fire up, you have spark under compression.

didnt work..
i know my head isnt bad.. thats brand new... but i may need a bottom end rebuild eh'?

 

[Tyeler18]

You said it sputters like it's trying to start? Have you checked your CTS (Coolant temp sensor)? When they go bad they will flood the engine out and cause it to sputter but not start very well, in a lot of cases adding starter fluid just makes it worse.

Another thing, have you replaced your plugs? They COULD be fouled out. Had it happen on my N/T. Put a new clutch in it and after 3 days of it sitting (didn't touch anything ignition) the shitty plugs that were in it were fouled out.

why would you need a bottom end rebuild if you have 140-160 compression? if you didnt have compression than id worry about a rebuild. is the fuel pump turning on when the key is in the on position? is everything plugged in?

 

[Brokstatus420aT]

You need a $5 can of starting fluid. Then move to a 15 dollar fuel pressure tester. Then possibly a Multimeter. They will collectivly save you alot of time and money in the future

Did you check to make sure your firing order is correct since you are using a CAS and have a 95 ECU which is programmed for the inverted cas on a 95. You will have to swap the Blue/Black wire and the Blue wire at the coil connector in order to have the correct firing order.
