I've chased my tail with this for to long. I purchased 98' Bravada & love this truck. Only problem is it has trouble starting. Once it's running it runs great. Doesn't matter if you drive 5min. or 5hrs. It takes about 5 to 20 key flicks to get it started. It runs rough for a couple seconds(like it's loaded up) then it's fine. I've replaced the sending unit, fuel filter, coil, cap, rotor, wires, and plugs. I'm getting 60psi at the fuel rails, but am still having problems. The check engine light just went off, not sure why, but I don't care it passed E-check. What I'm wondering is if there are known ignition switch problems for this year/model? Or could it be a crank sensor, o2 sensor, or some other easy fix? I would really appricate some input. Thanks.

Re: 98' Bravada Starting problems
Put a test light on your ignition feed wire to the coil- it should stay light in "run" and in "start" mode-- I once had one with your symptoms- that did not have voltage in start or crank mode- it was the ignition switch- I proved it by jumping 12v to the feed wire- and it would start up every time...

Re: 98' Bravada Starting problems
sounds like a dripping fuel injector causing a flooded condition. the cranking clears the excess fuel allowing the engine to start.

Re: 98' Bravada Starting problems
Does your fuel pressure hold at 60 for 3-5 mins. after you shut the pump off?
