(2005 4x4 SCrew) Was driving to town last Friday. I slowed down to go across a one lane low water bridge and when I started up the other side (slight hill), the truck began to lose power. I struggled to keep it running enough to get it to the side of the road. It then died on me. Could barely get it started once and it bucked and shook until it finally died again. Pulled it home (about 2miles) and haven't been able to start it since. It acts like it tries to fire,but that's about it. I did some digging online and thought it might be the FPDM, so I changed that--still won't start.

I can hear the fuel pump energize/whir then I hear a clunk--all seeming to come from the fuel pump area (I pulled the bed off thinking I would change the fuel pump).

Any ideas? I've got 187k miles on it with the original pump, so it wouldn't hurt to change it anyway. BTW...looks like I'll have to drop the tank anyway because the pump is about 3/4 under the cab anyway��.

All comments welcomed!!

Forgot to add that I do not have any codes stored that I can determine

 

What did your driver module look like when you pulled it? Did you just replace it or just pull it and inspect it?

 

Also did you check the fuel pump relay to see if it's still good?

 

The FPDM looked good when I took it off...no corrosion, etc., but I put the new one on anyway. I can't find a replaceable relay in my manual...from what I've been reading, is it soldered into the fuse box itself?

Also I forgot to mention that the fuel filter is fairly new (

 

Are you any good with electrical schematics? Also have you tried giving it a shot of starter fluid to see if it fires?

 

You're right, the relay is integrated into the fuse box and can't be replaced. Are u any good at electrical schematics?

 

And when you say low water one lane bridge, did you go through water?

 

No...no water. Just a one lane bridge over a creek. I'm not a great electronics person by any means, but i will have my cousin here this weekend who is a wiz.

Also, i tried editing my last post (didnt work apparently), but when i try to start the truck, i get the message "check gauges" displayed in the instrument panel where the odometer is.

 

Have not tried that, but i will tomorrow evening after work and reply back. Thanks!

 

Ok. When you try to start the truck I'd the oil gauge moving?

Just did a quick check, but the oil gauge does not appear to move at all.

Try the crankshaft sensor. That was my problem

 

Thanks, I appreciate the response, as this is frustrating...I miss my truck!! lol I will check that this evening as well, but should be ok, as I replaced it less than 10k miles ago at the same time I replaced my VCT solenoids ( my truck was wanting to stall when stopping at lights and new VCT's fixed it).
