did everything right on tps.. changed the injerctor out yesterday for 91 si it idles just no throttle responsce I.E. if i floor it at idle its doesnt rev up and doesnt choke out just

 

that's damn near impossible, your throttle cable is mechanical, there fore, either it opens your butterfly or it doesn't, even if you got no extra fuel due to some other problem, the air would still flow, which would just cause the car to run lean, have opened your butterfly manually from the t.b. or just "floored it" from inside the car?

 

not to be a smart *** but i did everything you could think of to get this to run, starter fluid re wired the tps wrong just to see if anything would work took fuel rail out of intake to se if the injectors fire they do but only at idle when i step on the gas the stay at idle mist.. thats why i think its the TPS, or ummm? man but nothing at works checked everything with ohm,volt meter nothing at all just doesnt run right. you name ive done it..

 

Have you checked the timing? I always knew you could run the PM6 and PG7 ecu's but I never heard of the PM8 being used...

 

with a light no but the TDC marks yes with on the crankpully and 7:00 on the cam gear

 

Shouldn't your crank pulley be at TDC and your cam gear should be at the "TOP" position and the 3 nothes at 3:00 and 9:00? maybe you should reset the timing.

 

i was told on a ex/si head witha dx block the seven o'clock position was need to for TDC the 3-9 o'clk for stock dx

 

I beleive someone already explained the timing to you. If your unsure check this thread out. https://www.homemadeturbo.com/forum/...threadid=16521
I'd go back and reset my timing if I were you, you could be off qute a bit.

 

whats make that funny is that i started that post and i still manged to put that SOB at the 7:00 pos. so moday I hope that my ride will quit being MIA an in active duty sir!! thank you for the help

this is a shot in the dark.. but make sure you connected the throttle cab;e
