Hey guys, so, recently I received my st205 engine wiring harness back from Dr Tweak, who reconfigured it 2 plug n play, in my 94 GT,
Just finished wiring up everything yesterday, and went 2 turn key, it was turning over very well, and strong! But couldn't get it to fire...not even chug a little bit, just turns over??? Which I am still happy about, considering I had no key start before I sent harness away 2 be reconfigured. I noticed my fuel pump is not turning on, but will turn on when spliced through the diagnostic box, ( you know, loop a wire between B+ and W i think, and pump will stay on all the time) I did this, just to see if I could start it, and even with fuel pump full bore it just kept cranking, even with fuel pump on.... Question is: What do I need to check so fuel pump runs properly?/ runs Why is my car just turning over, even with fuel present, must mean I have no spark i guess, changed rotor and cap a little bit ago, would that effect the timing, and starting sequence so much that it won't even fire, HELP PLEASE!! ( need input ). |

its +B and FP that you jump to turn on the fuel pump. try jumping it and then starting the car. if it runs, then there is your problem. but if it still wont start then you have an ignition problem
