put in new alternator

 

Fuel pump relay - maybe an intermittent fault?

 

Have you tried unplugging the MAF sensor - may be worth a try as these can throw up all sorts of issues and may not produce a code.

Dec.

 

thanks i will try it

 

i cleaned it but ill try unplugging it

 

That is a pretty hard stop for the ECM. The only one worse is the Crank Sensor. ECU will not be happy. Think full limp mode without the MAF.

If this were mine and the engine A) dies or B) won't start you have to go old school on it IF there are no codes.

It needs compression, fuel, and spark. Mechanically is has compression. So it is fuel or spark. The easy one to rule out is fuel. Do this by adding fuel manually. Starting fluid is one option (disconnect accordion hose, spray into it and quickly reconnect it, try starting it!). The other option is a syringe and fuel.

Adding fuel will solve the "Who". Then you solve the "why".

 

And what prompted all the parts replaced? What lead to these specific items?

 

Originally the car would start then stop after about thirty seconds i read a post that said it might be thr high presure sensor
replaced thrn would not even start then id read a post re fuel pump so i replaced the pump still no gothen a matr vsuggestrd thr crank angle sensor so guess, i replaced the sensor. Still no go battery is new and alternator is new as these were stuffed well thr alternator was anyways and now im head ****ed

 

See post #21 and add fuel. Report back.

Also, get a bluetooth obdii elm327 and Fusion obd app. Once download $5.00, but the lexus Toyota scion add on for access to PID data. Now do repairs based on facts.

 

sprayed starting fluid down in car started now to work out what the problem part is

 

Well it needs the correct fuel pressure to the port injectors and I know you said you replaced the pump. You might have to put a gauge on it. The high pressure injector rail can be read through the OBDII port.

What exactly was replaced in the tank? Was it only the pump motor or did the filter and pressure regulator get replaced? If no to the last two, I suspect the filter is hurting pressure and volume.

 

Filter and pump

 

Check the low pressure and see if it meets spec. With Fusion, you can monitor the HPFP too. Both are needed to resolve this...

 

Added starter fluid car started ran for about 15 minutes now has code 087 low fuel pressure if i spray starter fluid it will start then stop
