Hard Cold Start

[Kable]

Well fella, Its that time of year and the truck is the 90 5.7TBI.
Fresh tune up Plugs, wires, battery, cleaned the injectors, fuel filter, new starter all that good stuff

Its still taking really long to start. 10 seconds usually. Im about to start lookng at fuel pressure problems unless someone can point me in another direction.

I've rebuilt TBI, New fuel pump, and new coolant temp sensor, plus what you mentioned and mine cranks the same way. Have not been able to figure it out in the last 6 years

speaking of the coolant temp sensor. I just bought one. Where is the Idle Air Control valve or sensor? I guess i thought the coolant temp sensor was the IAC

coolant temp sensor is in intake beside thermostat housing and the IAC is. If looking at the tbi from the front of the truck is on the left side behind the tps sensor
