you probably have the wrong size tires. the trucks came with 235-85r16 and got replaced with 245-75r16, wich is about 10% on the speedo.

here are the steps. remove the rubber line from the top of the pump(red clamp) twist it with your hand, it may not want to come off. take 9/16 deep socket, remove the return black fitting. blow backward in your hand if you can, see what come out, then go get compressed air if you have access...

i agree with warthog but if you must drive use vacume from the pump and choke the size of the hose down as this will limit the amount of vacume to the trans. it will shift early and most of the time you wont even feel it. you can manually shift also to make sure its doing ok. the alternative is...

you could be right, here is how to check. remove the return rubber line from the top of the pump, has a red clamp on it. remove the fitting 9/16 i think. look at whats inside of it. blow it backwards with air and see what comes out. should be just fuel. re install it, crank the motor, should see...

there is no fire with a diesel, no spark plug, just compression. i think your batteries are run down from cranking. if you have weak batteries and spray ether usually the starter wont turn the motor, thats what scares people. if your batteries are not hot, use 12v jumper cable to another vehicle...

the main ground for inside the cab is right above the e-brake. you can see it , take it loose and check it. dim light at the corners is usually a ground problem . you should be able to check these with a test light. probe the hot and find a ground with the other end. fuel gage that reads past...

i agree, this is what i have handy to do most anything under the hood of a cucv. 5/8 15mm 9/16 1/2 7/16 10mm 3/8 merry christmas mark

i will and have done all those things except unplug power to the pump because i never had any reason to, and they will start and run without fuel. there is a guy on youtube that does that very thing. i read another post where people get air in the lines over night, truck will start cold in...

ive owned over 100 of these trucks, ive sold over 50 on ebay alone. ive never had one with over 50k. the 4.56 gears, the rough ride, and no music makes people want to stay out of them. ive had an 86 m1009 with 3600 miles. it was new!! i have right now an m1010 ambulance with 7800 miles. i have...

im in hutto, be glad to help you out after christmas. send me a pm and ill give you my number. ill bet i can get you going on the phone. ive got lots of parts for these trucks. im in the country and work at the house so im available anytime. thanks merry christmas

im sorry but you are wrong, ether will make it run without any evidence of fuel, its the diesel thats KEEPS it running when the ether is burned off. this is also dependant on good strong batteries and starter. for the engine to turn over with ether in the cylinder draws way more current from the...

ive had to do that before too.

thats why i said walk slowly back to the truck for starting or i should have said walk slowly.

i have a set of these courtesy of the border patrol. the plug says 28v 500amps. i estimate these weigh 75lbs.

we will disagree on this. ive owned lots of 6.2 diesels and most of the time when i buy them the glow plugs are not working. ive had to use it to get them going or to get home or whatever. in my experience they are always bad or not cycling. ( bad controller card). i dont like to use it but...

you dont have to hear anything from the pump, just check for 12v with the key on. if your seeing smoke at the tailpipe while cranking, you have fuel but no heat. i dont condone using ether but just a little bit will answer your question about fuel. in fact just squirt a little in the breather...

you still may have air in the line from when you pulled the filter off. if you have a test light check the output at the bottom of the glow plug solinoid. turn the switch, listen for click and see if you have power out of the bottom, where the big orange wires come out. if you do, there is power...

here are some pics. thanks, mark

if i knew what chip on the card controls power to the relay, i could fix all the cards i have . you can trouble shoot the card to a certain extent, i read it in some tm somewhere. i have seen his problem before, no current draw, no start.

i listen for the relay click first and foremost, (and look for current draw) if that happens, your getting juice to the plugs. (normally). in my experience, when the card fails, it doesnt energize the relay. i doubt any of the plugs are bad. i have a stack of bad cards that look good but wont...
