I have a 1999 sL2. It had been running fine but was a little hard at start up sometimes. I got an engine light a couple of weeks ago. It went off after a few days. Went to start it the other day and would just turn over. Have spark. Fuel pressure goes up but drops after a few seconds. Checked inside cylinders and they are full of gas. Dried cylinders out, disabled fuel pump and injectors and checked again. It was dry. I have not checked injectors yet, don't have a noid light, but wondering what chances are all four would be bad and stuck open. What are possibilities for other causes?

 

The odds of all four injectors going bad at the same time would be very high, I suspect. Perhaps your have a defective fuel pressure regulator since you say the pressure goes up but then drops. I'd try another one if it were mine, but I'm not a mechanic, so don't take my word for it. This is what Autozone shows. http://www.autozone.com/autozone/par...mString=search Get some other advice first before shotgunning parts at it though.

 

So whats the word?
