aperseghin Posted September 9, 2010 Share Posted September 9, 2010 the 88 4.0 efi auto does not want to stay started the first time i start it.. I'm thinking it may be a fault code or something similar. its a renix system. is there anyway to read the codes?? it starts then stalls right away and the battery light comes on , then goes off and it starts fine after that Link to comment Share on other sites More sharing options...
james750 Posted September 9, 2010 Share Posted September 9, 2010 Check your fuel pressure. Maybe the pump cannot produce enough fuel pressure at initial key on? Link to comment Share on other sites More sharing options...
carnuck Posted September 9, 2010 Share Posted September 9, 2010 Turn the key to on twice before cranking. If that works the fuel pump relay is probably going bad. I swapped mine for the AC one (it's there, but my truck had no AC. Go figure?) Link to comment Share on other sites More sharing options...

james750 Posted September 9, 2010 Share Posted September 9, 2010 There is an idler pulley and a bracket to hold said pulley on non-ac models, If you place the bracket and pulley in place of the compressor, then yes. Link to comment Share on other sites More sharing options...
