injector Question
Ok, I have done many searches and cant seem to find a problem similar to mine. First off, is there a way to ckeck the injectors to make sure they are working properly, out of the car?
My Problem.
Car will start after sitting for a day, but I have to use the fuel cut off switch to get it started, after its warm and driven, the car will not start at all. It is flooded, even trying with the fuel cut off switch and puling the Fuse. NOW, if i get another car and jump it with cables(extra juice) It will start with me playing the fuel cut off swithch.
The car: 88 TTII
new rebuild
new 720's secondaries
old 550's secondaries rebuilt and now in primarys
new battery
new starter
E-fan (less resistance on engine start up)
This started when I put the new secondaries in, and I am wondering if one if them is stuck open by any chance. That is why I would like to check them myself if I can other than sending them back out. Any opinions accepted.

no I do not have a SAFC, I do have a chip in the ECU to allow for fuel cut that was installed by the previous owner. And I do not experience fuel cut when the car is running. So what purpose would the SAFC surve on startup when only the primaries are being used and they are still stock?

This sounds like low compression to me.

Fuel injectors have a constant 12v on them. They operate by the ECU pulsing a ground to them. IF the secondary or primary had a constant ground on its ground wire........the car would never start and fuel would be constantly pouring in the rotor and pour out the exaust pipe and any place inbetween the rotor and exaust that would allow it. In short...ain't likely that one of the injectors is permanently grounded.

Sounds like a low compression problem to me. Depending on how the engine was rebuilt, what housings were used and what seals were used/reused, the break in could take quite a while...
A stuck injector is certainly possible (I have seen it), but is dreadfully obvious. Fuel will completely fill the engine, drip out of the exhaust (and all exhaust joints), leave a puddle under the engine, the car will never unflood, the intake will fill with fuel, etc.
