Question about 1999 Saturn SL
I have a four door 1999 Saturn SL2 Automatic that just recently started having electrical issues. About two months ago was driving in extreme heat, shut off to fill with gas, and would not restart. After sitting in shade for about an hour (jump did no good battery fine) it restarted and made it home and then died again. Helpful mechanic diagnosed it with testing meter to be Relay switch--and we replaced the main one and the one that controlls the AC to be safe (and even bought two spare just in case). Ran great for about a month. Then another scorcher....died....remote keys/alarm would not work/radio would not work/car would not start/ headlights work/interior light works/dash lights come on when try to start.....no fix when change out relay switches.....Let car sit for 2-3 hours....started and ran fine for 1-2 weeks (but radio/clock all reset)
Happened again today...very hot and humid...all above symptoms...towed home....called mechanic and described...he wants me to research too as he's stumped. Luckily home and so is car...and can borrow if can...research seeming to say to start with Crank Position Sensor? Does this sound posible? I'm sure it will be tough to test as by the time he can look at it, it will probably start again...and I do not have much knowledge or meters...I just need advice to help point him and not empty my bank. Any/all help will be GREATLY appreciated!!!
Hopes this help, found answer on Saturnalia
If your mechanic has a schematic or looks in the owners manual and checks the loads listed for the IP BAT fuse in the UHJB and they are all dead then its the F-5 connection. The fuel pump is a direct feed from the IP BAT to F-5 to the fuel pump relay. the fuel pump fuse is on the other side of the fuel pump relay.
It covers exactly what I am trying to tell you. Check the IP BAT loads, if all dead, fix F-5 and if the internal wire is burned open replace the I/P panel.

Instrument Panel Junction Block (IPJB) Removal:
1. Disconnect negative battery cable.

4. Remove screw and ground wire from H-bracket.
5. Remove wiring harness from H-bracket.
6. Remove screw and disconnect rear electrical connector from IPJB. Remove IPJB screw.
7. Using a small screwdriver, release lock tabs on IPJB and slide off of mounting tabs.
8. Feed IPJB through H-bracket towards front of car.
9. Inspect PIN F-5, circuit 402 on the Black 68-way connector of the instrument panel junction block for signs of arcing. If signs of arcing are present, replace IPJB and terminal. Refer to the IPJB Installation and Terminal Replacement procedures in this bulletin.
10. If no signs of arcing, verify terminal tightness using GRAY probe. Replace terminal using the Terminal Replacement procedure in this bulletin.
1. Feed IPJB back through H-bracket.
2. Slide the IPJB into mounting tabs and lock into place.
3. Install rear Black 68-way electrical connector into IPJB and then install screws in connector into IPJB.

Look at IPJB (Insturment Panel Junction Block) located in console area by shifter,Pin #F5 (Big Red Wire) for heat damage. chances are this is your problem.

Circuit 402. Loose terminal at the instrument panel junction block. Go to the back side, drivers side of the fuse block and reove the grey 64- way connector. A 7mm bolt in the center of it. Look at all of the connections, possible hot spots, if terminal F5 looks hot, replace the terminal and the fuse block.

Auto or manual? If its auto try puting it in neutral and try starting. If manual than try pushing the clutch all the way to the floor. There is a switch on thr pedal that when pressed it enganges the starter.
