Hello! Need Help New mazda family member.
 

Hello Everybody I love my 2004 mazda 3 been having it for 4 years. However I've encountered a problem that I cannot Fix. My 2004 mazda 2.3 hatch does not turn on but it does crank..I've checked the fuel lines,cam pos sensor,battery,alt,throttle body(had the at check engine light before but still always turned on). I can't figure it out! I have very low to no spark, plugs are new! low compression 120-90-90-120 psi this happend after a reppo took place. please someones advice in what i should do would be greatly appreciated. I've been told to just buy new engine but thats my last resort. Thanks Everyone. p.s Im working on repo company to pay for it..

Weak Spark with new plugs? Make sure the plugs are properly gapped and test the COPs (Coil on Plug).
Check the timing belt marks to see if they match up correctly.

You can also make a cylinder leak down test to find where exactly you are loosing this compression.
Check Youtube for videos on this. I think EricTheCarGuy has a good one.

Ok I checked and all plugs have no spark in all cylinders. I have and timeing chain but haven't checked for proper timing however, is it pssible for off timing to cause no spark and coil packs seem good maybe Ecu? Or pjb?
