Question about 2004 Dodge Ram 2500

1 Answer

Difficulty starting 1990 Dodge Cummins.

This has been the startin'est truck I've ever had and Ive had it for about 14 years. It only has about 175,000 miles. Recently it acts much like schmalfarm described. I already changed the lift pump, which made no difference; then the fuel filter and water separator. The latter helped a lot, but it still acts a bit like you would have run it out of fuel and then not bled it properly. I have pinched off the return line and let it sit for several hours and then did the same with the supply line. Made no difference; evidently it is not bleeding back, and I can see no leak.
What could be the problem?

    Don't think it could be the glow plugs. I normally did not use the pre-heat except in cold weather and it fired right off. Now the weather is hot.

Should i replace audi 2008 a4 thermostat along with timing belt and water pump 120,000 miles

I would - but the timing belt would be overdue at 120K if a 2.0L engine. From the service interval linked below:

"At 110K miles (175,000 km) replace timing belt (2.0L engine only). Check condition of timing belt tensioning system, dampening pulleys, and idler pulleys and replace if necessary (2.0L engine only)."

I've recently purchased an 88 ford bronco with a 5.0 that had been sitting in a repo yard for about a year. after replacing a fuel pump and filter i was able to get it running. it idles well and s

The first thing I would check is the park brakes coming fully off when released. If the units are rusted and stiff you will have dragging brakes which will give the symptoms you describe. After all it has been sitting for a year with the park brake on.

Check engine light came about 175,000 miles on truck

This is a cross over year between the use of OBD I and the OBD II computers, regardless I would bring the truck to a Auto Zone parts store they read the trouble codes for free and should be able to retrieve the trouble code and point you in the right direction rather than you or I trying to guess.
