also spark plugs are dry even after trying to turn over the car for awhile.

 

prime the injectors and try again also check the tps make sure is calibrated

 

tried no luck, tps is calibrated.

 

you sure you got spark?

 

yes have spark.fuel pump is working, have fuel pressure. have good comp. the only thing that I can notice is the plugs are dry even after cranking several times.

 

what if you spray some starting fluid thru the intake?

 

havent tried that.

 

do the leds on the unit light up? green for power, yellow mimics ign output, red for any errors.

 

checked for errors all ok.

got green and yellow no red?

 

spray some starting fluid , and check your coolant sensor . might be reading wrong
