Question

I have an 88 IROC (5.7 liter / 700r auto) that has a starting problem. Here is some of the history around this problem: I haven’t started the car in several months and yesterday I started it (very slow but it did start) and moved it from my back yard to the street and shut it off. Then tried to start it again and the starter wouldn’t turn the motor over. It just “clicks”. Tried jumping it, no go, replaced the battery, no help. Today I pulled the started and solenoid and bench tested the complete assembly, and both of them seam to be fine. Solenoid does it’s thing and the starter spins. Voltage gage reads about 10 volts but the battery is charged (both batteries).
Does anybody have a clue as to what could be wrong?
I have code reader, but that won’t help now, the battery has been disconnected and the memory on the computer has been reset. I have heard about the starter / heat problems on third gens and I think that could also be part of the trouble, but it always started before.
Thanks

Update: 10/3/00
Remove the started again, and thought that the starter was bad (just not enough torque to spin the motor) and replace the starter and solenoid, new rebuild unit does the same thing as before.
Checked continuity of GND cable 00.0 ohms. Starter(repair shop) people claim that there is a relay some where in the circuit, but my manual shows nothing like this.
Hey friends, I’m stumped, Does anybody have any suggestions?

I don't know about the differences in your starter system as opposed to mine (in a '68), but I had a very similar situation about a year ago. Worked ok one minute and the next, no start... it actually turned out to be a fried battery cable. Again, I don't know if this is exactly your problem or if this info can help at all, but if this is the problem, it is only about a $5 fix. Good luck.

Talking

Thanks boodlefoof, I think that is my next thing to check. Starter shop said to re install starter and then hook up 12V (directly to solenoid) to it then do a “bench test” on the car to see if it will spin the motor. Then that will tell me if there is something else in the circuit that is the problem. Cables are cheep, like you said.
Again, Thanks for the help.

I hope that is what the problem is... probably the cheapest one to fix.

yes there is a starter relay in your starter circuit. it is located behind your left kick panel below the hood release. usually has some black sticky insulation on it. hope this helps!!!!!

Thanks trickster! I re-installed the original starter after checking a lot of connections and still no help. I’ll have to take a look for the relay that you are talking about. The only good thing that I can say about this right now is that I also fixed a connection for 1 of the 2 electric fans, now the fan works like it should. What dumb luck….

at least the effort produced some result... even if it wasn't the starter.

greetings Z28 [email protected], glad that I could help you out with that info. Had same thing happen to me recently. I don't know what manuals you have, but the haynes and chilton manuals just were not giving me enough to go on. I went down to my Chevrolet dealer and had him order me the maintenance service manuals for my 1989 Irocz. These manuals cover all the models for that year and are very comprehensive. Also has diagnostics and wiring schematics. Also gives locations of all components for each vin model.

To me, for the information they contain, it was well worth it.

Again, Thanks trickster! I may just have to obtain a dealer type manual as you stated. I’m using a Haynes manual and it really sucks wind….Well I’m back at it to day, I would like to drive it to night, we have a Camaro Club meeting tonight, and I don’t want to drive my F*rd to a Chevy meeting.

Problem Found!!! I added another GND from the battery to the alternator (just a convenient place to clip the jumper cables) and the motor turned over and started.
So boodlefoof you get the title of MVH (Most Valued Help). I just need to let the motor cool down a bit and change the NEG battery terminal cable.
But really, THANKS TO ALL, This is a great web site to ask questions and to get some help when you need it.
