just got done puttin on my new exhaust and the car ran fine for 2 days then today at work it wouldnt start when i was ready to leave.... heres the situation, just put on lt's, prochamber, catback, splitfire plugs, changed oil and filter two days ago. i drove the car into the garage at my work and then drove it out to the parking lot with no problems.. half hour later i walk out to the car and it wont start. the car turns over but wont fire up. the fuel pressure is at about 35, the fuel pump primes, the distrubitor is dry ( very wet out so i checked) , i have spark, all sensors and vaccuum lines looked connected... any one have an idea what could be wrong???
