    We also have a Savana that keeps blowing 25 amp fuses. When it blows the van stops dead cold. What do we do to find the problem of blowing the fuses. The box is on the right side by the window washer fluid.



    Thanks

I had same problem, the origanl owner replaced the fuel pump and when reinstalling the gas tank they had wires wedged in between the tank and frame shorting it out...also i had wires that went over the dip stick for my tranny fluid shorting out on it... check that first you never know dont take much to short a wire out...

Relays get hot and thats normal but the fuse burning might be caused by a defective 02 sensor or oxigen sensor disconect sensors and see if keeps blowing the fuse
other cause of burning fuse might be injectors but if you had a mufler or exaust repair latetly most likelly 02 sensor is shorting

    okey if you try to start it again when it is cold most likelly it will start right up, get a fuel presure tester or have some one to check the fuel pressure before and after the problem there

    most likelly when you fuel pump gets hot it will not pump the right amount of fuel,

    you might have to replace fuel pump and fuel filter

    one of the first cauces of fuel pump failuers is due to lock of service to fuel filters

    i hope and this help and go ahead and put the 02 semsor back

Keeps blowing engine 1 fuse when I try taking off. I put new fuel pump,computer,and shift selector on and even had it at the dealership. blew fuse 10min after leaving dealership


Did you check the crankshaft position sensor ! This get's power from ENG.1 fuse 20amp in under hood fuse box . What engine does yours have 4.3 L ? Eng.1 fuse powers up the crank sensor like I already said but it also powers up the oxygen sensors ,mass air flow sensor , evaporative purge solenoid , evaporative vent solenoid . I don't want you to think I'm talking down to you or anything like that but Do you know what each of these parts are that I listed ? One of these is shorted somewhere ,check the wiring for the O2 sensors , they live close to exhaust pipes an manifolds .I have seen the wiring for them melted on manifolds etc.. Take hold of the wiring harness a wiggle it in different spots with it running see if stops running ! I know you would like a little more of a definitive answer but with problems like this you need to take a good look at the wiring ! Good luck hope this helps !

1999 1500 gmc savana wont start, it ran great, parked and now in the am it did not start...amp is good but oil gauge is low, we already add oil to it, it needed 2 qts...please help


May I ask how long since the last oil change? 2 quarts low is some serious oil loss. You are going to have to do some basic troubleshooting. Start by checking for blown fuses. Next, check to see if you are getting spark to the spark plugs. If you're getting spark, then check for fuel delivery. Do this by cranking the engine with the starter for a few seconds. Then pull one spark plug and see if it is wet with fuel. Let me know what you find and we will go from there. Good luck.
