stalled, died, will not restart

[newwagwheeler]

Please help, my DD is dead. 88 gw with amc 360 sputtered and sputtered on the way home after it got to operating temp. 105 degrees today here in s.e. MM. Then it stalled, a few times and died completely. Will not restart now. I have plenty of gas... in the jeep. Please throw ideas this way. Vapor lock? Maybe... how to cure?

Check for spark/ignition. if you Know you have gas & see it spraying when you pump the accelerator.

I am subscribing to this thread. I want to see what others post. I have gotten a lot of advice about an electric fuel pump. And, I have also been told that the electric fuel pump will just mask over the real issue. Just wanting to read more...

The electric fuel pump will resolve hard starting isses IF the rest of your fuel system in in perfect shape it doesn't fix everything. Simple logic No one puts a manual pump on any new vehicle for a reason.
Aways possible it's vapor lock or other unperfected issues. A little information causes massive speculation. Assuming he has gas at the carb then you could elimnate that issue.

Well the fuel filter was too hot to touch... like burned my hand hot. Put a bit of starting fluid in the carb and she started right up. Moved the filter away from the manifold, so we will see how it works tomorrow.

definitely sounds like a fuel pump. You can get a new Carter pump from rockauto for 23 bucks.

Actually just added one to my order, feel like thats could be the next thing to fail...

Find a way to either reroute the gas lines away from the exhaust or insulate them. If you can't touch the gas filter that is way to hot.

I have had a couple wagoneers that vapor locked in the summer no matter what I replaced/did to them. I used to have a red '91 that vapor locked when it was over 90 degrees no matter what. I basically replaced everything and it couldn't be cured. I never put on an electric fuel pump though. The '89 I am driving now never vapor locks. I remember as a kid in 1991 when my mom had a brand new 1991 Grand Wagoneer that it vapor locked on a road trip to Santa Fe in 90ish degree heat on the side of the highway Good times

I know that my wife's cj likes to vapor lock.

There's a manufacturers design flaw with the fuel lines running right next to the exhaust. Then people make it worse when the change the filters & get the system even closer. If you re route the lines or insulate them it will help stop. An electric fuel pump can actually help but it is not the misconcieved only solution. I rerouted mine when I put the Edlebrock carb on it. I routed the line back around the fenderwell to the fire wall & across the forewall to the right hand side of the motor. I have no probs.

fuel line insulation

.... If you re route the lines or insulate them it will help stop.

Curious what the best insulation method might be. Is there a 5/16 or 3/8 seamed equivalent to the stuff used for copper water pipes?

[serehill]

well you could sleeve rubber hose over them.

Wrap them with foil insulation similar to water pipe stuff. Get some exhaust wrap which is most popular I've seen.

Could this be a failing ignition module?

[newwagwheeler]

By the way, this problem has just recently developed. I have not made any changes since last summer and it did just fine in the extreme heat.

Then that's reliable evidence you probably don't have vapor lock.

Need to verify you have spark. Put a timing light on the coil wire and see if it flashes when cranking.
