Have you check all fuses for 12 volts both sides? The pull in voltage is about 8 volts for a typical Bosch relay. Should I try to replace the fuel filter relay? In this video we discuss common no start diagnostic strategies. On fuse check always check for power on both sides key on. So you say starter is new as well as the relay. This acts like the old fashioned Choke.
Should I try a new battery at this point? Run a small wire from the small wire connection on the solenoid up towards the positive battery terminal. Attached a fuel pressure gauge to the fuel line in the engine bay and no pressure was being generated. The security system if it has one only cuts off injectors after a 2 second run. Have fuel coming up to the pressure relief valve. I spent 3 weeks checking power grounds etc, totally sucks. Check your battery cables at the battery for corrosion. All fuses are good inside the fuse box drivers side kick panel.
Im kinda glad its over. I have that wire on my car and leave it on there all the time. Could be the torque convertor on it's way out. I am going to replace fuel filter. Thanks, Yon I have 2 of the exact same truck and both had that problem. Replaced the fuel pump, dist. Oh, it's under the distributor cap and also controls your Fuel Pump.
That will narrow down your problem. If you should need further assistance go to my website by clicking here: Mar 19, 2015 Assuming it is a 4L60E trans. Our van , just cranks. If you still get the click it is the starter or flywheel lock up. Sometimes that will jolt the pump into pumping. Any suggestions would be greatly appreciated Thank you. I could be wrong, but these specs should apply.
What is mileage and last tune up history? It turns over good battery and starter work fine. Also it takes a minute or so with the key off for the computer to reset again to hear the pump running. Went today and got an ignition switch. Report back on spark and fuel pressure. I also put a scanner on and it would not connect or link. Since then it won't start unless we use starting fluid, and even then it won't stay running. If you have a strong spark, then it is a fuel problem.
Marty Yes fuel pump is in the gas tank. Have you done a relearn on the pass-key? Let us know how it goes. Any check engine lights or codes? What would be next step? I don't know where to go from here Please help - Kevin S. Verify by reading voltage at that small term while you try to crank; easy way is to read voltage between the battery term and the small one. I was just thinking about what the old man said. I will end up replacing it with the new one.
Why that causes the hard starting in wet conditions is beyond me and when I ran across this issue on chevyforums I thought it was hard to believe that would fix it. I blew it out with air and sealed it with silicone. Thanks everyone for the responses! What would be next step? If the battery is good, need to separate whether you have an ignition problem no spark at plugs or a fuel problem no pressure at fuel rail, no pump running, etc. Engine Performance problem 1997 Chevy Express V8 Automatic 180000 miles 97 chevy cargo van. It has not started since.
If no start always check for good hot blue spark to all spark plugs and for spark out of coil. Watch part 2 of this saga here: If you have helpful tips to add please comment below. This module although working is well on its way to do the same thing as the old one. I will continue to look around to see if anything is chewed or frayed from my recent fuzzy visitor. Tried putting starting fluid in the air filter would fire up then die immediately. So my question is: what more should I check before I give up and get it towed? Ill post my results later once I get it changed. That should be about equal to battery voltage when not cranking, and the go to near-zero when trying to crank.
I am pretty sure you have the schematic, but will post it anyway for others who may hit this thread. I was told it could be a pass lock problem. The current draw by the coil of a Bosch relay is ~0. To check for ground can I pull ea fuse, and go with meter pos to device side of fuse panels with out shorting out ecm vcm ect. I am out of ideas heeeeelp.
No wonder I had so many issues. Cap and rotor, spark plugs and wires, changed oil and filter and air filter. After new computer it runs smooth and fine, then the probelem starts all over again, have checked timing, checked all the grounds and put more ground wires. Turn key off, then start it. Pull in Voltage: The pull in voltage is the minimum voltage required for the relay coil to pull the contacts 30 and 87 on the Bosch relay together. Jumping red wire and purple wire at starter relay will rule out any neutral switch problem anyway, as the neutral switch is in series yellow and black wires of exciter of starter relay.
