Several issues with my truck I would like to get fixed.
I have a '95 PSD 2x4 with 245K miles on her. When I bought the truck, I got her for $2100 and knew it had issues. She was neglected by an oil field worker for a long time apparently. I have been getting her back together and every fix I have done has made an improvement. Here is what I have done over the last 2 years and some of the issues I have that I would like to get fixed.
With the cold weather here, I am having the same problem as a lot of people. Hard starts! But, last year I replaced all the glow plugs (6 of them were bad) and replaced the GPR which was bad also. Still had to plug it in if the temp dropped below 50. This year, I did some troubleshooting and decided I had several injectors that were acting up, missing at all rpm ranges, barely running when cold, etc. The injectors I installed are stock so there is no modifications. The truck is running tons better. The day after the install, it was 50 and it started without being plugged in. The night I took it to work (70 miles round trip, 75 mph 60 miles of it) to bleed the air out of the system. That next morning it was 28 degrees outside. Truck started and drove like it should when the systems work as they should. No issues. OK, where is the cold start issues? Right here. I let the truck sit for 2 days, yesterday was 53 degrees outside, went to start her and no start. Cycled the system several times, approximately 6 times and still no start. Plugged her in for about 30 minutes and she fired right up. What else could be causing this type of problem?
When I change the oil, I also drain the HPOP and change that oil also. I know some people say that is a snake oil fix, but it has made a difference on this truck when it comes to starting issues.
I checked the fuel pressure and when it was cold and running, it was 40 psi. When it was at operation temp, it bounced between 45 - 55 psi. Also had a leak on the filter cap. Got 1/8 of a turn on the cap to tighten it. Haven't check to see if it stopped the leak yet. These pressures seem low, what should they be? Has anyone done the "BB" trick to help a failing regulator? Could that be a fix for my low pressure until I can save for the proper parts?
Could a faulty/plugged IPR be causing these hard starts?
Open to any suggestions, comments, questions, etc. and would like to get this fixed.
Another issue... Brake pedal bleed down. The brakes will start off good and do great for normal driving, but if I press hard on the pedal, it will bleed down. It's almost like a timed reaction also. It will hold for a few seconds and then start to bleed off. I have never waited to see if I loose all braking power.
I have read that this is a common problem but have heard several fixes and none of them are cheap. I have put a new system on the truck. Being able to stop is just as important as being able to go. Here is what I have replaced:
brake booster (Auto parts store brand, have been told a zero loss is what I need?)
front steel lines
all 3 rubber lines (2 front and 1 rear)
front calipers and pads
Rear pistons and shoes
I have also removed the ABS for the rear brakes from the system and is no longer hooked into the hydraulic part of the system
Both these issues aren't real big problems, but would like to get them fixed.
Open to all comments. Please help.
