Zoltan Posted September 16, 2014 Share Posted September 16, 2014 Car is stock and starts fine when cold, and also starts fine when fully warmed, but only after siting for a few minutes after being fully warmed up. When fully warmed and engine siting for around 20 to 30 min she does not start easy. She will start after 2 minutes of cranking with the pedal to the floor and then she will run ok. I had a spare MAF,and replaced it. That did not change anything. Thanks for taking the time to read this and will greatly appreciate any help.

Dee2 Posted September 17, 2014 Share Posted September 17, 2014 Carburetor or fuel injected ? Quote Link to comment Share on other sites More sharing options...
silverhelme Posted September 17, 2014 Share Posted September 17, 2014 He's running a maf so you can assume SPFI or turbo MPFI. Check your temp sensor ( the one for FI not gauge ) most of the time this is the hot start problem. Quote Link to comment Share on other sites More sharing options...
MilesFox Posted September 17, 2014 Share Posted September 17, 2014 engine temp sensor, the one with 2 wores, not the single spade. especially with MPFI engines Quote Link to comment Share on other sites More sharing options...
Zoltan Posted September 17, 2014 Author Share Posted September 17, 2014 It's a SPFI, I unplugged Coolant Temp Sensor (Green plug) during the hot start problem and the problem did not go away. The next day with the engine fully cooled down and the CTS still unplugged I went to start car and it started and died right away. I am thus assuming CTS is working ok? or am I making and incorrect assumption? Thanks for taking the time to help, it is much appreciated!

Zoltan Posted September 18, 2014 Author Share Posted September 18, 2014 I checked the ECU codes and 34 "EGR" comes up. Does anyone here think that this may be causing my problem? , or is it just unrelated. Car is a 92 Loyale SPFI non turbo Auto FWD and has only 110 000 miles, engine runs fine other than above mentioned problem. Quote Link to comment Share on other sites More sharing options...
Cmosfet Posted September 18, 2014 Share Posted September 18, 2014 Hi, i am still learning but i had that code when i got my 91 loyale wagon. It means the egr solenoid control valve is bad. Either electrically opened up or a bad connection. From what i have read, the computer just checks for resistance of the coil in the valve and if it does not see it it thows the code. I hear they go bad all the time. That one and the purge control valve. Same type of valve. I think the egr does not do anything untill higher rpm or load, like when you let off throttle while cruising? Other gurus will know more on that. Hope that helps somewhat Quote Link to comment Share on other sites More sharing options...
Zoltan Posted September 26, 2014 Author Share Posted September 26, 2014 I changed CTS sensor did not help. I put a thick ground wire from the ignition coli bracket to the neg on the battery. Still no change. Since the car starts fine when hot for the first 10 to 20 min, but starts hard after 30 to 40 min heat soaking, I am assuming it may be a fuel problem. Its SPFI and I pulled the boot off the top of the throttle body after I turned off engine to see if fuel is leaking slowly and flooding it out over 30 to 40 min. I cant see it leaking, but I seem to have convinced myself it is a flooding problem. Is their another way for me to check if the car is getting flooded? Appreciate the help!

Zoltan Posted September 29, 2014 Author Share Posted September 29, 2014 Seems the problem was the TBI slowly leaking fuel after it was warmed up and flooding engine. 1 Quote Link to comment Share on other sites More sharing options...
