Lakesong Posted September 22, 2015 Author Share Posted September 22, 2015 Put original cam sensor back in car . Still no spark.checked all connections,vacuuming hoses etc that I disconnected when swapping out temp sensor . No spark. What could I have done when swapping out sensors listed above that would create no spark situation? Original problem had spark would fire and run first thing in morning but stall just before reaching operating temp( gauge almost at normal operating location but thermostat I don't believe open as radiator still cool,not pressurized). I'm afraid to try anything else until I know why no spark now. Any ideas? Quote Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted September 22, 2015 Share Posted September 22, 2015 could a bad cat be clogging the exhaust as it warms-up? weird I know - maybe check with a vacuum gauge. There are 2-3 things a vacuum gauge could help find. was crank/cam timing checked? maybe the crank sprocket has shifted on the crankshaft?

lstevens76 Posted September 22, 2015 Share Posted September 22, 2015 Check and make sure the crank sensor is plugged in and is tight. Have you pulled codes to see if there is a code relating to no spark? Quote Link to comment Share on other sites More sharing options...
Lakesong Posted September 24, 2015 Author Share Posted September 24, 2015 Checked codes and sure enough showed crank sensor circuit issue. Found one of the leads broken. Fixed that. Now no code, but still no go. Cranks strong but.... When I pull a plug wire ,put in one of the plugs I just replaced and ground plug to engine I don't see a spark like I did before replacing sensor. However a shot of starter fluid and she fires up and dies, wouldn't that indicate a spark? Anyway I'm gonna take everything apart that got moved when replacing the sensors mentioned above and make sure no other connections where compromised. But then what? Fuel pump?, computer? Anything else? Any way to test before swapping out with my parts car? Quote Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted September 24, 2015 Share Posted September 24, 2015 I get confused about models sometimes but, look for a largish rubber hose loose from the intake - it comes from the IACV on the throttle body.off 1 Quote Link to comment Share on other sites More sharing options...
Lakesong Posted September 25, 2015 Author Share Posted September 25, 2015 All hoses connected securely. Does fact engine fires and then dies with a shot of starter fluid mean I have spark even though I don't see spark when I pull wire put plug in it and touch to manifold while cranking?

Fairtax4me Posted September 25, 2015 Share Posted September 25, 2015 If it fires, you have spark. Quote Link to comment Share on other sites More sharing options...
johnceggleston Posted September 25, 2015 Share Posted September 25, 2015 firing with the starting fluid means you have a fuel issue. and this is too late, but the crank triggers spark the cam triggers fuel when it does start, does it idle high or low? does it idle? or ju8st fire up and then die?

Lakesong Posted September 28, 2015 Author Share Posted September 28, 2015 Won't start now but before I swapped out sensors would start when cold idle at between 1500-2000 as engine warmed would idle down to @ 750. As approached normal operating temp but before thermostat opened(radiator still cool) would idle down to @ 500 and then stall. Would generally only crank but not fire after that. If I shut her off before it got hot enough to stall was able to restart. When she fires up now ,with the aid of starter fluid, she only runs about 5-10 sec and dies. Giving it gas does nothing.

Lakesong Posted September 30, 2015 Author Share Posted September 30, 2015 Okay ,got her going. Rechecked fuel flow before filter. This time nothing, explains why not c arching at all. Swapped out fuel pump from parts car and bam she's good . Have run for 2 days now,put on over 100 miles .no issues. Problem solved. My guess was when I checked fuel earlier ,when she would start but die when engine warmed and idle dropped,fuel flowed but didn't gush ,pump was failing, still pumping gas but not enough pressure. So would run when cold and idling high enough to keep from stalling but when warm idle dropped and she starved and stalled. Does that make sense. Pump finally quit altogether creating no start at all situation. Any way the dogs are happy one as am I. Thanks to all for your. Input.
