hello everybody. i have a 1999 accord lx ulev vtech 4 cyl. 120k+. the car was stalling and hesitating so i sprayed carb cleaner into the throttle body and while that was sitting check the cap and rotor. replaced cap, rotor, air filter, pcv. the car will not start. tried several times. took the plugs out and saw they were fouled. cleaned them with brake cleaner. still no start. i have to clean the plugs at each attempt to start. they are coated in wet black carbon (not oil) but it is hard to tell if it smells like gas. i rechecked the firing order 5 times , tried starter fluid, even loosend the fuel line. gas is flowing and i do have spark. it seems to come so close to starting then you get a slight backfire from the tb opening . even tried the old cap and rotor, new plugs. got tired of cleaning the old ones. any ideas?

 

Hello! i have same problem,and i have inspected belt timing too,and injection time when starting and it is about 43ms,is it ok or too much,ECM was
broken but it is fixed now but still car does´t start?Main relay,distributor cap,rotor,wires,are changed,fuel pressure is ok,TB sensor,temperature sensor,garankshaft sensors signal are ok!? souds like ecm is broken?!has anyone used ecm ??

 

i took out the main relay and inspected it with a magnifying glass. no bad contacts. i've searched on the web for a couple of days with no success. probably get it towed today.

 

are you sure you have good fuel pressure ? this part sounds fuel related almost like a failing fuel pump. but then you said....

this sounds like a classic timing issue. have you checked spark at each plug wire ?
