good afternoon my name is ***** ***** I will assist

make sure your fuel pressure is good. you can rent a tester at a parts store.

the crank sensor is responsible for pulsing the injectors. see if you have a rpm reading while cranking

Hi, My Name is ***** ***** for posting your question to just answer. I am a independent contractor for just answer, and ASE Certified Master Auto Technician with 20 years experience. I am confident we can resolve your problem together.Please remember I don't know your skill level. I can't see, smell, hear, or touch the vehicle. It may take a few back and forth replies to get to a satisfactory resolution.There will probably be some equipment needed for a proper diagnosis. If you are not comfortable with this or do not have any test equipment please let me know ASAP. I also try to give all of the information you may need expecting a positive rating. I am not compensated for my time until you leave a positive rating.

Do you still need assistance?

If you hold the throttle wide open when cranking it will put the vehicle in clear flood mode. release throttle as soon as it starts.
