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.

 

Well without a SAFC or some method to control the bigger injectors I bet you'll flood a bunch. You didn't mention if you had one.

 

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?

 

Any other views on this?

 

Well, the secondaries shouldnt be firing at startup, so I dont think its an issue. What it sounds like is a possible low compression/bad starter issue.

 

Has new/rebuilt starter and only 3500k on a rebuilt motor. After car starts up it will not hold an idle until about 2-3 mins warm up time.

 

when i had low compression, it would start up without any problems when cold, but when hot, i was required to use the fuel cut-off switch.

 

FSM page 4B-74.

The stock fan is not going to make starting the engine any harder.

This sounds like low compression to me.

 

if the negative wire of the injectors is pinched and grounded they will fire constantly.

 

Does this include the secondaries on startup?

NZConvertibl, TY on that info, i will look it up.

 

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.

 

i have seen it. yes they will start and run for a little if one of the secondaries is firing always. i will bet you (hailers)that this is the problem.

 

Ok.

 

TY, since I did upgrade my secondaries, and had to add a resistor, so maybe I made a kink somewhere there. Ill look into it today.

 

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.

 

intake looks dry when I cheked injectors and the wires to the conections. Everything tested/loked ok. next step compression test I guess.
