I was driving home when my 97 tj broke down, it just died. Had the jeep towed to the gas staion where he said that i needed a tune up the connections were coroded. They sanded the connections so I could get, home. I started to drive home and as soon as i got on the highway the car died. Had it towed and once I got it off the tow truck it turned over. I replaced the cap, rotors and wires and all seemed to be fine.
I drove approximately 45 miles and it died again, the mechanic said it was the crank shaft sensor, replaced it and told me the fuel pump was broken. I purchased a used one din't want to pay the $300.00. I replaced the fuel pump today and the jeep still doesn't work. I can't tell if the pump is cycling, but does anyone have any ideas.
Thanks

Same exact thing happened to me last night (for the 2nd time) and I have to have it towed to the shop again today. I just had my fuel pump replaced and the crankshaft sensor had been replaced as well. A couple people suggested it could be vapor lock? But another guy said that's not something this Jeep has (?).
So possibly fuel injector? Hopefully I find out today & will update this post! 馃憤馃徑

Considering the fact that there are six fuel injectors (common rail vs single point) not likely.

Any codes being set?
Check wiring behind engine by the oil dipstick tube & firewall. IIRC that's a known friction point that can wear the insulation off the wires.

usually there are no codes without a light, depending on the reader you might be able to see the old codes that have been cleared

I had a weird issue with my battery connection. Just bought my Jeep and brought it home, it would not start and my millenial son said to check the battery connection. We wiggled it and sure enough... it started.

Update: I found that if I put it in neutral I can start it. I quick put it in drive and go to keep the RPMs up. When I have to slow down, take a turn or stop I put it in neutral before to maintain RPMs. Could it still be the ECM?

I hate to step in on an old thread, but you have to start at the beginning. Spark? Injectors getting signal, fuel pressure OK? And codes, even if you don't have an check engine light on. There are plenty of youtube videos on 'no start' type problems. And yes, it could be crankshaft position sensor, TPS, but from my house, I'd check/clean all my grounds. Good Luck!
