Once again, my car is on its time of the month and has decided it does not want to start. Turns over fine with plenty speed, spark present, fuel present, however, still will not start. Any ideas what to do? Car is a 1995 Spi. Diagnostic has been plugged in and annoyingly, all seems normal. VAC lines are all in check. Help?

well if there's sparks and fuel then all that's missing is air!! but unless the air filter is completely blocked then unlikely that. Perhaps the spark isn't happening at the right time - crank sensor?

As said above take the air filter off and try?

[crazypainter]

they have a problem with the fuel pump live dropping out if that helps

[IainStallard]

Air filter off and tried to start it but nothing still. Fuel pump is all good. Will clean the crank sensor tonight to see if that makes a difference

Running again now! But for how long? Managed to get it going by jump starting it and after constant turning over and a lot of coughing, it fired into life! However, I am thinking that something is amiss. Any ideas people?

Maybe your battery is on its way out and isnt holding a good enough charge to fire the engine

[IainStallard]

Battery seems fine, turned over fast enough. Only jump started it because I had worn the battery down from trying to start it so much

coolant temp sensor?

coolant temp sensor?

Temperature gauge moves as normal so seems ok

[hunterg30]

check all the water ways in the intake manifold are clear, also plug the diagnostic machine back in when the engine is cold and see what temp readings it shows.

i had a similar prob and it was the temp sensor not working properly,the ecu was not reading the engine was cold so it did not alow for this when trying to start

[IainStallard]

All sensors seem ok, coolamnt temp and air temp seem as normal.

Car starting easily on the key now but it seems rather under powered :/ however, that might just be me coming from my TVR at the weekend

[Twincam]

Seems stupid, but is there a possibility you may have flooded it?

The sensors are weird beasties. They may seem ok, but there is only one way to check, stick it on a diagnostic tester and read the live data. Also check earth straps in the engine bay and the boot and ensure they are spotless, lubricate with copper grease.

 

You can't just assume that it seems ok.

[IainStallard]

I have been reading all the live data on the diagnostic and all seems correct to the conditions outside
