my battery is fantastic but at times the starter will not engage, could this be a problem with the steering coloum/ingnition switch or do you think starter is screwed?

I was charging an iceless cooler and the charger to the cooler was hot when I unplugged it after the radio stopped

A mechanic put in a Rebuilt engine. Van runs awhile but won't start after 15-30 minutes. it has to sit 40 minutes before it will start again. has new Alternator, Starter, Water Pump, Radiator, Battery, and full Tune up kit.

Van starts up and runs fine when cold. Sea light stays on. Once truck is up to speed it runs fine. When I give it gas it has a misfire. Temp needle doesn't move above 100.

it looks like a cover for something fell off and now it's spinning and grinding when I drive it. It's not the alternator I don't know what it is it's not my vehicle I just Need it fixed.
please help

Problem continues,have to puul fuse

i changed the fuel pump i checked the map sensor with bobby pin no change i also checked oil sending unit changed fuel filter and i cleaned the throttle body and injectors. i checked all the fuses i am stumped and wondering.

5 o v8 it acts like it starving for fuel at take off then it runs great after it picks up speed? New air and fuel filter, has 60 thousand miles.

It has power to switch when off its 12v on shows 4v and to starter, but doesn't engage when cross jumping the sealenoid

This Chevy van has the side-by-side 4 headlight system. I could swear that I'd seen all four lights on when the hi-beams were on before, but noticed recently that switching on the hi-beams turned off the low beams. A mechanic told me that some 4 headlight vehicles are designed to do that, but as I say, I could swear all four lights used to come on. Maybe I'm simply wrong. Can anyone confirm one way or the other?

It acts like it just loses all power.

and how to perform best resolution.

wont shift out of first.will manually go in second. and speedometer doesnt work. checked sensor and changed for the spedo pretty much checked everything ,so I thought

I read there may be wires connected to things on the Dashboard and elsewhere on the front seats, as far as I can see there is not much the passenger seat does as compared to the driver's seat and it does not have the electrical buttons the driver's seat has.

Do you think it is safe to remove the front passenger seat? Thanks!

I have tightened the battery cables once and it came back on.

Recall 98v033000

Linkage doesn't engage reverse. Drove 600 miles w/ no problems,slipping or noise. Reverse just went out. Need to know how to diagnose or what trans fit this van or how to fix it. Please.. thank you

It will not start back up until it sets for a while
I replaced the ignition modulator, rotor and cap

Been having some issues with rear end noise when shifting from P to D and while driving from 1st to 2nd gear. The u joints are good but there is play in the driveline. Has 150,some odd miles. Should I replace the whole rear or just the gears and bushings?

Am having a problem with the brakes on my van. Had new brakes installed about a year ago so they are in good shape. I don't use the the van that much so there is not much mileage on them. Just recently my pedal slowly started to go down to the floor and the brakes were not working properly. I took it to a friend of mine who is familiar with doing repairs on trucks. The first thing he suggested was to replace the fluid. At the time he said that the valves to drain the system were kind of rusty so we slowly started to drain the fluid from the filler cups. He did this several times while sucking out the fluid and putting new fluid in it. The old fluid was black. I left van at his house so he can work on it in his spare time. He has a garage with a lift in it. When we took the van for test drives as we periodically changed the liquid to see if the brakes would work. One thing I forgot to mention was when we step on the pedal it would go down to the floor and then all of a sudden the brakes would suddenly catch all at once and stop the van. My friend bought a master cylinder figuring that that was the cause. There was not much of a change at all. So the problem is somewhere else.Since then my friend sprayed the drain valves and was able to loosen them up.
We plan to drain the whole system and put in new break fluid.
This van break system has two parts.One for the front and one for the back.one filler cup is small and the other filler cup is larger.
