I added some BG 44K fuel system cleaner to my car a couple weeks ago and seemed to be running great. Went through that tank of fuel and refilled at the sunoco station. Every cold start it will only crank and wont start unless I push the skinny pedal. Any relation between the two? Once it starts I get a quick puff of greyish/white smoke from the pipes and then its fine. If I let it sit all day at work 7+ hours it will do it again. Any ideas?

 

you need to service your injectors.(get them cleaned).

 

I garage for the winter and don't have the time or money to get my injectors serviced before winter. Any tricks I can use without removing injectors?

 

Maybe a leaky injector? May want to add a fuel pump kill switch and turn the car off that way.

 

It seems the cold weather is playing a factor. It went from 60+ to less than 40 in the mornings. I start it every couple weeks when it is put away for the winter and it acts like this when I try and start it. I have to let it turn over a few seconds then give it some gas and it starts up.

 

It was 60+ degrees this saturday and I went for a drive and it started up no problem. Cranked about 2-3 seconds and started with no help of the skinny pedal. Can the cold weather make a fuel injector leak? TPS is adjusted for 80+ degree weather, could that be playing a factor?

 

The TPS is set when the engine is completely warmed up so after it's set the air temp is irrelevant as far as that sensor is concerned. The Water Thermosensor regulates to an extent how much fuel is injected as a function of the coolant temp so you might want to check that sensor. Pin 2E would read 2 to 3 volts w/key to on and engine cold and the voltage drops to .3 volts w/the engine fully warmed. And as already mentioned, if your starting problem is directly related to when you added some fuel additive it might have fouled your injectors (at least the primary injectors).

 

Thanks for the tips I will have to look into these.
