Guys, just wondering if anyone might be able to tell me what's wrong with my car. It just dies in mid-drive. The fuel pump keeps running strong (it's brand new by the way, had to replace it for other reasons), and none of the other systems seem to respond to this. It's not like when you stall out and warning lights come on for oil pressure, voltage, etc. No, nothing like that. It's like the car doesnt "realize" it's not running. After a few seconds of this (usually 5-8 seconds, but sometimes longer) it just back-fires through the intake, and takes off strong as ever. Anybody got any ideas?

What are your "few bolt ons"? Sounds like an ignition problem to me. Whens the last time you did a regular tune up?

i had the same problem with my 88. i replaced the coil and it's been fine ever since. there's instructions in the haynes manual on how to check it with a volt meter but the coils are so cheap and it's not a bad idea to replace it anyway if the one you have is old.

It has a MSD Blaster coil (which I,ve replaced twice already with good coils that I know work), GT-40 upper and lower intake, BBK cold air, TRE Performance 255 LPH fuel pump, MSD cap on ford distributor, 8mm wires, can't think of any thing else fuel or induction related.

you did replace the fuel filter too
Mine has done that a few times too. It hasn't done that since I replaced the filter.

Yes, I replaced the filter when I put in the new pump. Does anyone think (and I hope It's not) the brain box going bad?

I got a customers that does this some times I took the ten pin connectors apart cleaned them up real good and it has seemed to have gone away. some times it would not start also and I would grab the wire harness and shake it and it would start up this is how I got to cleaning the 10 pins. his was fuel not spark.

Guys, I am "Automotive electrical system illiterate". I don't know what the 10 pen connectors are. Sorry, but I would be very grateful if someone would tell me.
