When I initialy start my truck it starts fine and I can drive it with no problems. But when I shut the engine and try to start it again it wont stay on. It will crank over like it wants to start but dies down. I have replaced the Module, coil, fuel filter, plugs and wires, cap and rotor, and the throttle position sensor. I don’t know what else to check? Please advice
Since the problem only happens once the truck is warm, I would check around the engine for any loose fittings or hoses that might have expanded and started to leak once they were warm. It would probably be a big leak to keep the engine from starting entirely, so open the hood with the engine running and listen for any hissing or sucking noises. Pay particular attention to the intake manifold. A vacuum leak can wreak major havok on an engine’s ability to run. Another possibility is a faulty O2 sensor. It will be plugged into the exhaust on the engine side of the catalytic converter. It’s possible that that is reading wrong once it heats up. From the parts you say you’ve replaced, the only thing left to check is whether or not your fuel line pressure and flow is adequate. It’s a pricey thing to replace, so I would get a fuel system testing kit from your local auto parts store and check that your pump is delivering adequate pressure AND flow. (Though a good kit is also expensive. It may be cheaper to just replace the pump) It would also be a good idea to make sure none of the injectors are sticking, though a good dose of a fuel line cleaner can usually remedy that.
What I would start with is the symptoms of why it doesn’t start. Is it getting fuel on the second crank and spark? Thats where i would start from and post results and we can go from there!
It might also be your ignition relay. Usually it isn’t smart to just throw parts at a car but after looking at all the parts you already replaced a ignition switch makes quite a bit of sense to me.
could be a timing problem,check the timing after engine is hot.
Got same problem on my 94 i have put new fuel pump, massair, an ingition switch an relay. I have found out that when it want crank there is no power to injectors for some reason. Help
try replacing regulator in fuel tank if your car is hard to start when hot ,worked for my 2007 toyota
There’s some great suggestions in here, you can use the Toyota repair manual as well for bolt torque specification and for issues you cannot figure out yourself. Have a look here: toyota hilux 1989-1998 repair manual
Most likely your radiator is not keeping your engine cool enough so i should check the hoses and wires like the other guy said and then take it to a auto zone, o’reilly’s or some time of a place like that’s near you then ask them to check the radiator and if it’s faulty then just change it also they will know if the the hoses could messed up as well and they should check it for free.
suggest replace alternator and/or battery
