Ive looked around some and one anwer is that the fuel rail gets to hot and boils the fuel before it gets into the cylinder, is this possibly true?

Try replacing the coolant temperature sensor for the injection system.

SOURCE: wont start after warmed up

here are things to do.

Clean MAF sensor wires with carb cleaner and toothbrush carefully. This will remove varnish.
Check under distributor cap and rotor (1 screw) and under slotted plate. If brown dust, you need new distributor. Clean optical sensors for cam sensor before re- assembling. Temporary fix only.
Check ECT, engine coolant temp sensor.
Have Autozone run free computer scan for fault codes.

My 1989 prelude is skippingh and sputtering


I had a similar problem. it would run great when the motor was cold until it started warming up. and then when i'd give it gas to get speed up it would act like it was either starving for gas or getting too much. I first started at the fuel injectors, pulled out the fuel filter and dumped it out, gas looked dirty so i replaced fuel filter and it didn't fix the problem, i then checked the fuel pump but it was ok. next i pulled the fuel tank and when i pulled out the pickup tube the screen at the end was clogged and their was chunks floating in the tank. Cleaned it all really well and havent had that problem since. hope this helps you

Your coolant system aint heating up like it should. Its your thermostat. You need to change it. its broke. There are four parts to your thermostat. You need to make sure that you get all four parts out. A thermostat costs about five bucks. Its an engine temp. regulator. If its broke your engine wont warm up at all. If it seizes shut, your engine will overheat. Your thermostat is broke. I Have the exact same car that I have been repairing for the last three months.

1989 Cabriolet Fuel Delivery problem


yes,it's your computer module
it's dying or so.
it's the one cutting off the fuel system
i've seen that more than once
the fixer it's to replace the module.
but first to be sure.
unplug it for about 10 minutes.
then plug it back on
and test it and see what happens, if it runs fine for a while then definetly that's your problem.
or have your computer checked.
