Question HELP!!! PLEASE

Just got my '96

Drove it home and it ran great. tried to start it the next day nothing

I thought it was just too cold (for you southerners it is cold in PA) I replaced the GPR and Block heater plug. Then found the batteries were weak, replaced them.

Now it just cranks faster but still nothing. It is definitely warm enough. I can feel heat coming of the block.

I unplugged ICP still nothing.

WHAT NOW????????

Next would be to check the fuel pressure. On the driver side if the fuel bowl you will see what looks like the end of a valve stem use a stick style tire gauge and check the fuel pressure while someone is cranking the truck you need a min. of 20 psi to run

When you're cranking with the no start, are you getting white smoke coming out the tailpipe?

this happened to me when i bought mine the guy i bought if from just got done doing a oil change when i came to buy it and he didnt put enough oil in it. there is a sensor in the oil pan that when your oil gets to low it wont allow it to run. so check your oil may not be the problem but its worth checking.

There is no sensor in the pan. When the oil is low is gets air in the system and wont fill the hpop res.

I KNOW it will not run if its low on oil, ask me know I know. The computer will shut it down if it see's no oil presure. Also like Jeffrey says, so sensor, no run. No HPOP oil, no run.

I would also say check the oil first. Easy to do. MY F250 died a week after I got it and wouldn't start. Turns out the last one to change the oil didn't put enough in. After adding oil it started right up.

You said you waited until the wts light goes out,you need to wait about 120 seconds,the wts light is just a indicator.

Did you check the maxi fuse und the hood? I think it is 22 that runs the idm.. It is also on the same circuit as the fuel bowl heater.. It often goes out in cold whether.

First I have about 25-27 psi at the fuel bowl.

I am getting some white smoke out the tail pipe.

It was low on oil when I bought it (a gal. low) but I added oil before it wouldn't start.

I am waiting long enough on the WTS light.

All fuses on the truck are good.

How cold is it there? Have you looked in the fuel bowl? It isn't gelled up is it?
