95 Tacoma Trouble Starting When Warm

Is that something that would be effected by temperature though?

ive seen some weird stuff caused by bad battery cables. if it were me i would def try replacing them. a relatively cheap replacement that might work.

I do think that this may be the problem that I am having. Because the problem is fixed when I disconnect the IAT sensor which make the computer run the engine rich. The problem returns as soon a I reconnect the sensor.

If you want to check your own fuel pressure, how is that done. According to my shop manual you need a special banjo fitting and bolt to stack fitting on the fuel rail. Are there any after market parts for doning this?

Thanks,

The EFI relay was at fault.... In my case

RE: Fuel Pressure testing I purchased a INNOVA #3642 Fuel injection Pressure Tester

I have an AVI video of my starting problem if you want to download it.

I'd like to see it and compare to my truck
