if the car dos not start within the firet turn it floods the motor and wont start.I puli the efi fuse and krenk it dry,put the fuse beck in and it starts ok runs ok .no codes any more the a/f ratio at idle is 14.6 and under boost is at 10.5 to 11.5 im boosting at 15psi low boost and 20 psi high boost.I just have the flooding issus.any help is good help.tx:1zhelp:
flooding problems on 87 7mgte

- Start date
Its possible, if the injectors are leaking. I've seen it on a few Saturns and more recently my Dad's Ford. Try starting it while holding the throttle all the way open. If it starts up when you do that, I would do an injector balance test.USPturbo89;1351862 said:

What does your temperature gauge do when you drive it? Does it show it getting warm?mk3junkie;1351910 said:
I was thinking if it thinks its cold, it could be dumping extra fuel in for a cold start condition. If the gauge is always reading cold, an open in the ECT sensor circuit or a bad ECT sensor could cause that. But it seems like that's not likely. What about your fuel pressure?mk3junkie;1352023 said:

Double check that, but I doubt that. It runs once he can get it started. So I was already doubting fuel pressure as well, but always good to check.shaeff;1352062 said:
So far we know:
It is getting too much fuel
Fuel pressure is good
Injectors most likely are not leaking
It is not an ECT sensor related issue
I'm running out of ideas. I'll have to go research a couple things.

Will it still start if you pull the EFI fuse and clear the fuel out, and then start it?
-AM3
yes if i pull efi crenk it fo 30 sec put it in it will start but not oll the time. the injectors are rc550cc
Check the cold start injector time switch. It is located on top of the T-stat housing, and has 2 wires going to its connector. Resistance should be as follows:mk3junkie;1352095 said:
<59* F.............25-50 ohms
60-84* F..........51-59 ohms
>85* F.............60-85 ohms

Do you mean the correct cylinder? Or that the two wires to each injector backwards? Would it matter being a simple coil?
Leaky cold start injector?
i just checkt the fuel pimp resistor operating resistens is 0.70 mine is at 0.00 ohms.ithink thet is the problem ill pick one up next weak and go from there
What, is that what we call gas station attendents now? LOL.mk3junkie;1352482 said:
Hope that fixes it.

i dont know if it os gooing to fix it but im getting one on wensday so will see i allso chekt my solinoid resistor it is sopost to be 3 ohms my is showing 6.5 ohms.i am just going to replace it to and go from there
