Okay when we first got the car it would start almost immadately. Now you have to crank it longer to get it to finally start.

have replaced in the last year
o2 sensor
Idle Air controller
Spark Plugs
EGR Valve and solinoid
Cap and rotor
Wires are good (look brand new )
injectors were cleaned on a machine
New Air filter
Fuel filter
Oil and filter

ignition control module?

Fuel pump relay or possibly the fuel pump itself.

Also replaced fuel pump last year. But I will do a pressure check. I will check the relay.

Ignition module. Will get one this week. ANd also a new coil

Did you do the correct procedure when installing the IAC motor, it should be in the tech section. Aslo have you checked the fuel pressure? and finally I've had very similar problems with my 91 formula 350 and when it would start happening I would remove the throttle body and clean it throughly inside and the problem would seem to get better. Hope this helps

Yes followed the procedure. It just recently started with this problem.

Got ignition module yesterday will install.
