When it dies out immediately do below to determine if its fuel or spark causing it
Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 in away from ground have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,coil's resistances,cap and rotor /distributor pick-up coil, ignition control module, ECM,Ignitor camshaft and crankshaft sensors and computer. Note: If it doesn't apply disregard it
Thanks for that - it has good spark, and good fuel pressure (new plugs, air filter, new fuel hoses either side of new fuel filter, new dissy, new coil). I have tried fuel (without spark for safety) and the pump is fine, good strong jet doesn't stop. Pulse on injectors is OK checked with noide light. Just as before, starts well, stops after a few seconds. Any sensors you can think of would lead directly to this problem?
Clean out the idle air control/mtr/ISC and MAF sensor with an approved cleaner and test TPS sensnor.
Does anyone speak normal english? mtr/ISC?MAF/TPS are not words!
Mass Transit Railway
International Standards Certificate
Ministry of Agriculture and Forests
Toyota Production System?
So much acronyms Huh!
Clean out the IACV ( Idle air control valve ) The MAF is the ( mass air flow sensor) and the TPS is the (throttle position sensor) -Good Luck
thanks, will do as advised and keep fingers crossed, if I can find them! have a great day
The IACV looks like this its on the throttle body
Same goes to the TPS at the throttle body, for the MAF sensor -check the airflow meter
For the IACV change it to : idle speed control bypass valve solenoid.
thank you for your excellent and in depth assistance, much appreciated
