Gen II Swap Guys -- Fuel Pump Prime Options

[Fastbird]

For you guys with the Gen II GTE, do you have a circuit wired up for your fuel pump to prime for 2-3 seconds with initial key on engine off??? I've noticed that on a cold start my car has a mofo of a time starting and I can't hear the pump prime or anything. Car has to try to suck fuel through the system to get it going and it sucks. I never bothered to notice before if (when stock) the pump was wired for a prime or not when the key was initially flicked on, but it sure doesn't now and makes for difficult cold starts.

Any help would be appreciated. Trying to get the last couple little things straightened out on the car.

when you say hell of a time cold starting do you mean it takes a lot of cranks and then fires up first try, or doeds it fire up, die, then fire up, die, then finally fire up and stay starting?

if this is your problem then its probably your cold start time injector switch, 21 or 22mm sensor on the coolant neck, behind the coolant temp sensor for the ecu.

mr2.noegruts.com has a picture of the coolant neck if you need it.

It doesn't long crank at all, but it will BARELY stay running, chugging and lugging right at the point of stalling out, then after maybe 3-5 seconds tops it'll catch and idle up to a cold idle like normal. Sometimes though it will die and will take one or two more times of this process and then it'll fire up like normal.

I completely forgot about the colt start injector. So you're saying there's a switch for this?? Any way to troubleshoot that?? Would it throw a code?? I presume it's in the BGB, could anyone post up a scan or something possible if there is a diagnosis procedure?

Thanks Brian, I do appreciate the response.
