I am sorry your having this problem

did the car die when it was jumping the other car ? did the car shut off and now just cranks over ? or it will not crank over physically ?

Customer: replied 12 months ago.
Car did not shut off while jumping other vehicle. It ran fine for about an hour after while running errands. Once it was shut off for about 2 hours it would not start.

and adding starting fluid will not work ?

does it have spark when cranking it over ?

Customer: replied 12 months ago.
I added it in air filter and it didn't work. Yes has spark when cranking
Expert:  Gary replied 12 months ago.

these cars are not supposed to be used to jump or be jumped as with all the modules in these cars any voltage spike can damage the BCM or the PCM very easy and cause very odd issues like this

the next step would be to see if a scan tool can communicate with the PCM and the BCM and if so are there any codes set in either module

Customer: replied 12 months ago.
The scan tool said no codes to be read.
Expert:  Gary replied 12 months ago.

for this engine to not fire up it has to be missing spark or fuel or compression for it to not run

Customer: replied 12 months ago.
Any suggestions on what i should try?

Tyne rpms move when I try to start and The enginelight is on
Expert:  Roy replied 12 months ago.

ok, the crank sensor is working and the pcm is working.

I would check the fuel pressure next. you can rent a tester from a parts store.
