2001 Toyota Hiace Regius Need Meaning of Engine Codes

hello everyone just joined, I have a 2001 Toyota Hiace Regius 2690cc Petrol/lpg, had a huge problem starting it we have replaced the plugs and crankshaft sensor no joy.

I have just purchased a scanner and was wondering where i could find the meaning of the codes the scanner not arrived yet till tomorrow but like to be prepaired welcome any help please thank you

look into https://zf-scantools.com/ and his products
look into j2534 cable and techstream
look into shorting diagnostic plug and counting ECU light flashes on dash

I'm not sure if the Regius is OBD2, OBD1 or even M-OBD. The Super Customs are generally OBD1 or some are M-OBD.

If the Regius is OBD2 then the reader will probably convert - if not, then they're readily available online. If it's OBD1, then the flash codes are online too - eg: https://www.2carpros.com/articles/toyota-trouble-code-definitions-and-code-gathering-method-1990-1995

If you've ordered one of the zf scantools devices, the more basic version (ODB1READ) doesn't fetch codes, just displays computer sensor valies. The 'bigger' one will though (TOYOCOM). I think he's only making the more basic version now but the other comes up for sale now and again on the TOYOBD1 facebook groups.

BTW - what are the non-starting symptoms? Hot engine, cold engine etc?
