2002 Vauxhall Astra no start

HI thanks for your reply! Well I tested the fuel pump on a battery and it was working, when I depressurised fuel system before removing pump there was no pressure or fuel squirting out at the rail. However since I put new pump in there is pressure and fuel there. When I tested old pump on battery it did not work so I thought I was home and dry! I cranked car it started ran for 2-3 seconds then stopped. Now it just cranks over and wont fire? Originally it was firing with easy start before I replaced pump but that was more like a misfire it blew my air intake pipe apart at the flexi joint! Perhaps this was the cause of the random misfire code? Thing is I don't know how old these codes are as I recently had the car given to me by my nephew he told me it was fine before he parked it up, just that it sat for about 12 months I have changed Fob Battery reset key but no luck yet. I have been told that crank sensor sometimes brings up same code as cam sensor but I am really out of my depth trying to Fathom these things out! Any help or ideas what basic tests I might do to determine where the fault is before I buy tons of new parts would be greatly appreciated! Thanks! Jim. :O)

Hello again :o) I squirted the starting fluid into the carb and it fired up for 1 second then cut out. Got that noise like a misfire too? I was thinking of changing out the spark plugs, but does this test indicate that I am getting a spark? My very limited understanding would suggest that if I have fuel at the rail, my pump and relays must be ok? And if it fires up even for a second with starting fluid I must be getting a spark? The codes I got in the order they come up (if that makes any difference) are: 0340, Camshaft? Position sensor incorrect or no signal? Then I get 0230 Twice? Fuel pump secondary circuit high c-07? And/or Fuel pump relay open circuit c-07? Then after the level sensor code I get the 1230 twice? Main relay voltage high c-03? And /or Main relay open circuit c-03? At least this is the info I have looked up on internet but you probably know this already! Sorry if I am going on a bit just wanted to be sure I have given you all the info I have to date! Very much appreciate all your time and effort trying to help me! Anything else you need me to check just ask. Thanks again Jim. :O)

Hmm could be a bit of a problem that, I don't have the gauge needed to check pressure. And don't know how to check the regulator, whatever that is? Lool As a Layman maybe if I tell you that when I depressurised the fuel system prior to removing old pump there was no pressure or fuel as I think I said earlier? However I tried this again after I fitted new pump by pushing in the small valve on the rail and the fuel squirted out with a lot of pressure. Therefore I think the only thing we can deduce from this is that there is not too little pressure? My next problem is I am afraid I do not know how to check the injectors? ( Let me take a moment to apologise for any headaches I might be causing you Lol ) And Ahem at the moment I cannot find my darn sparkplug spanner! I have been looking for it last couple of days but I will go buy a new one and check the plugs ASAP doh! Just to make it worse I have to go into hospital for a small operation on my hand Thursday so I have few things to do and may be a bit delayed making checks? I will keep checking back here though in case you have any suggestions how I might go about doing the other tests you have mentioned. All I can say for now is I might be thick but I am willing to learn! Lol Thanks again Jim. :O)

Thanks Joe! Very interesting video and info. I will look into renting the tools I need over the next week or so. I need to get this surgery on myself sorted 1st (Carpel tunnel surgery Ouch!) But as soon as I can I will get stuck into it! I will keep you informed of any progress and hope to talk to you again soon. Thanks for your regards and help greatly appreciated, talk soon take care. Jim :o)

Hello again Joe. If possible could you take a look at the following Ebay links and advise me if these tools are the correct ones for testing fuel pressure and injectors?

Thanks! :O)

Hmm I have a mk4 Vauxhall Astra 1.6 sxi 16v. Seems that all the noid lights say for testing injectors, looks similar to one used on the video? Although I am not even sure how to access the injectors yet I think they are under a long plastic box next to the fuel rail? But I have not as yet worked out how to remove it! I will contact seller and ask him meantime like you say. Do you think either of the following 2 items will do the fuel pressure, The 1st says fuel injection tester and the 2nd fuel pump pressure tester? I am close to buying a bicycle! Lol Thanks Jim. :O)

Ok Joe thanks a mil ! Take some well deserved time off while I get myself sorted out! Lol Will get back to you in a week or so with any progress? Thanks again for all your help talk soon take care. Jim :o)

Oh very interesting point that Joe, when I replaced the pump I did notice that the fuel inside the tank was very grubby! I did replace fuel filter, old one was in bad shape, but never considered age of fuel. Think I will make that my first job drain the old fuel and see how it goes! Not sure how long hand will be out of use though just yet having the operation tomorrow so hopefully wont be too long before I can do that? And yes! Liverpool UK here! Top gear is a very popular show here too! Its been said in the news today that his contract wont be renewed! Oh well Jeremy if all else fails perhaps I can give him a job as a star in a reasonably broken down car! Lol Take care Joe talk soon! :O)

Hello again Joe. I survived! Although the bandage on my hand is bigger than my head! Lol 2 weeks before I get stitches out but in the meantime I will siphon tank in the next few days and put some fresh fuel in see how that goes? Take my advice if you do ever come to UK try and come in the summer. Although I don't know what DAY summer will be this year? Lol Take care Joe talk soon. :O) Jim.

Wow 20 below! Don't think I could handle that! Never mind hopefully the good weather is near by for both of us now? Going to get back to car in a few days darn hands been aching like hell! But will get back to you in few days maybe with a update, Take care Joe talk with you soon. Jim :o)
