Not insulted in the least bit! I will take ALL the help I can get. I'll check these at lunch today.

Thanks guys. It has been a crazy weekend +. A family member died and the funeral was yesterday. I should be able to get back on this soon. Thank you for the suggestions. Todd

I tried a new PMD and still nothing. Any other suggestions? I will try to crack open an injector to see if the IP is pumping.

How would I check the PMD?

Hey Guys, My 1999 Suburban would not start this morning. The batteries are fairly new 5-6 months old and the motor turns over just like it always does (starter probably good too). I am getting fuel at the fuel filter and the oil pressure comes up while "cranking" it. My fear is the IP, but it...

Can anyone give me feedback on old style vs new style fuel filter? I am hesitant to try the all-in-one plastic fuel filter. Any help would be appreciated. Thank you, Todd

had to use four wheel drive a few weeks ago and ever since then the front axles seemed to be locked like it was stil in 4 wheel dr. The lights on my selector switch did not work so I replaced the switch. When testing out the new switch I managed to get her stuck in 4 lo. I purchased an encoder...

Not a problem. Thanks for the help! I don't get many likes because I am usually the one asking for help.

UPDATE!! "BIG GIRL" IS RUNNING AGAIN! After a very long process, my Suburban is running again. As Will L., Paveltolz and AK Diesel suggested, my final problem was a fuel problem. The fuel line that feeds up to the "front" of the IP was too short and was pinched and restricting fuel. She runs...

AK, No dash lights/codes being set. And no unusual things other than shutting off. When you say ignition switch, do you mean the switch where you turn the key?

Will, Thanks for the replies. It is difficult to ask the technician at the shop to perform these tests. It makes it look like I think I know more than he does, when clearly, that is not the case. I suggested that he check the fuel pressure, but he kind of blew that idea off. Can pressure at...

No, unfortunately, that was not it. I am not getting any codes, but the motor shuts off after running for about 30-45 seconds. On restart, it runs for about 10 seconds before shutoff. The shop that I have it at is going to look at the parameters on the scan-tool and make sure it is all in...

I was able to find a PMD locally and the guy let me borrow it.

I just want to plug it in and try it and give it back. I can compensate you for your trouble. I just don't want to buy one if I don't have to.

I have done this twice on my 1999 Suburban and I am just a shade tree mechanic.

After about 6 months, I am getting closer to getting my Suburban back in running condition!! At this point, it will run without throwing any codes, but cuts off after a few seconds. I am thinking that it might be a fried PMD. I had some wiring issues that could have possibly fried the PMD...

I replaced the IP and that got rid of the other two codes. I did not get a chance to look at the truck last night. Maybe Saturday afternoon.

ok, thanks I will try that also.

It runs for about 30 seconds to 1 minute then shuts itself off.

After some wrenching, far above my comfort zone, I have taken care of two codes (P0251 & P0370). However, I now have code P0335 (Crankshaft Position Sensor). I replaced the sensor with a dealer AC Delco one and had the same code. I convinced the dealer that I had a "bad" sensor and replaced it...
