Hi, just found this site and hope fellow Mazda owners can help out [&:]

Our Premacy (a compact? people carrier-petrol) has an intermittent starting problem. Sometimes after a journey it won't restart, it just cranks over. If I wait 5-10mins its fine and starts up OK. It also suffers momentary fall in power on the move. It doesn't seem to have this problem from cold (first start of the day). It also starts right away if jump or push started.

Could it be the fuel injection relay? coolant sensor? (picked up these from other motoring forums). If so, how can I test it, where are these items located in the vehicle and is the best way forward to replace these?

Have failed to track down a workshop manual for this model. Don't think one exists!

Help appreciated, local garage can't do much to find the fault as there is no code stored in the diagnostics!
