alright just like the title of this tread says my sr20det red top isnt really starting right now

i really dont know what it is... i have tried basically everything up to my knowleage....

1st. i check to see if the battery was dead and it turned out to be very good still

2nd. i checked all the fuses under in the driver side kick panel and it was fine too

still the car didnt start

3rd i checked the starter but it is working fine because the motor turns without a problem but it just wont start!!!....

4th. so i check to see if there is fuel coming into the motor and running through fuel rail at all and there was plenty of fuel there
and from here i thought it would be the fuel filter so i decided to change it alone with all the fuel lines that feed into the fuel rail

in the end with that done still was turning the motor with no luck of actually running.....

5th i checked all the ground wiring and it seems as if there was nothing wrong with it at all .... the wires were perfect with no cuts or anything.......

in the END THE MOTOR DOES NOT TURN ON!!!!!!....
its funny when i am driving on a smooth road the motor is running fine then when i hit a bumpy road on the FWY or something the motor starts to choke or something like that where the rpm at 3000 jumps back and fourth between 3000 and 2000 rpm. ... I REALLY DONT GET THIS AT ALLLLLLL PLEASE HELP

o yea the fuel pump works perfectly fine... checked that tooo...

help please

MAFS wiring bad? that would definitely do it... i had a similar problem with one of the SRs I did, when I didn't use good connections to the Mafs, which bounced around in the engine bay. Definitely worth a check ~

ur foot could just be bouncing on the pedal when u hit the bumps. no joke. i dont know what your suspensions like, but in my car, on bumpy roads its hard to keep my feet steady on the pedals. as for the not running, check for spark. also, just so you know, your title says "ahhh my SR IS starting up!!!"
