It cranks for about 3-5 seconds push the pedal down and then it starts. I have changed the EGR valve due to a fault code, still the same problem. Any help would be appreciated. The fuel pressure is good while cranking, it is giving 55 psi while cranking.

This system is very pressure sensitive and some won't even run under 55PSI. If what your describing is that it won't start with with your foot off the throttle but it does as soon as you crack the throttle open, then you could have a bad IAC (idle air control). ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional. deputy New User Apr 28, 2010, 6:32 PM Post #3 of 5 (1374 views) Re: Starting problems Sign In And of course I am guessing that its on the side of the throttle control body?

Sidom Veteran / Moderator Apr 28, 2010, 6:42 PM Post #5 of 5 (1369 views) Re: Starting problems Sign In One easy thing you can try 1st is to clean the throttle body. Get a little brush, a can of throtle body clean and open up the throttle plate and clean the bore and plate real good. You can start it up and spray some cleaner down the throttle body to get all the dirty but this will probably set a low MAF signal code that will need to be cleared..... I believe that one has a throttle cable so it will be easy to clean. If there is no throttle cable, extreme care needs to be used to open the throttle plate. Too much force can cause the gear to jump a tooth or 2 and then it's gets very expensive........   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
