i gota 92 cam. 305 tbi. ? is. when i start it or when its already running, sometimes it acts like it has a huge cam and kills itself. it can happen when i first start it or 15 minutes into a drive. has new tune up. also when it starts acting up the service engine light comes on. last time it died on me i had to pump the foot feet to get it to start. any help would be great, thanx

 

check for codes

 

checked codes its code 15 and code 44. l noticed last night that when i start it. the injectors act like little toilets. dump a bunch of gas and quit. so is it the injectors or fuel pump?

 

code 15 indicates -DTC - 15 Engine coolant temp sensor error (low temp indicated) and code 44-DTC - 44 Left bank O2 sensor error (lean condition indicated). Hows your gas mileage? I would bet your car is stuck in open loop now.

 

you may have one or more bad injectors. test them for ohms. Also, take a look at your o2 sensor,when did you change it last? it could be bad. Test your coolant temp sensor,or better yet,just get a new one. They are only like $12 at Napa. Don't rule out the possibility of a bad ecm either.

 

replacing fuel pump. pressure is low. also doing injectors next week. god bless cheap parts on ebay. if that dont work my buddy has a ecm out of a 90 tbi that ima try. cross ur fingers it goin to be a busy week
thanx everyone
