HiTech Posted December 27, 2022 Report Share Posted December 27, 2022 98 tahoe 5,7 i ussualy figure these issues out ..but this one has me stumped ..... was running great ..fuel pump went out change it went head and changed the injectors and distributor as well fixing this truck up for my brother who is in bad health and and cant afford much of anything ..so three bothers and one sister is helping me finance the repairs i am doing all the work .we bought it cheap has 127 thousand on it and sat for three years with front damage i fixed ..it has ran all summer everytime smooth as ice till i was ready to give it to my brother it starting having issues ...... SO with all that said .. it will not start up for the last week or so .. it has fire it has fuel pressure .it is in time the scanner shows nothing really wrong with it that u an stick a fork in 5 volts .the starter was loading up so replaced it and cables .. when i turn it over it will not start not even try .even with starting fluid .but will and i know this has happend before on the chveys fire off three revolutions after letting the key off .. the coil will spark three times after .. . i was told it was the ignition switch .so 128 bucks later still the same .crank sensor is working cam sensor just under 2degrees retard .. .. ... 60 psi ......battery was replaced with a new one .. i would love to get this truck to my brother his old truck is about dead and he lives in the country ..and it is not easy to just take off and pull him home ...any ideals i still have a few left in me but i would rather have some input ..

TBone Posted December 27, 2022 Report Share Posted December 27, 2022 Are the plugs wet when you try to start it? It has fuel pressure, but are the injectors firing? Quote Link to comment Share on other sites More sharing options...
